## How do you solve number word problems?

To set up and solve number word problems, it is important clearly to label variables and expressions, using your translation skills to convert the words into algebra. The process of clear labelling will often end up doing nearly all of the work for you.

Number word problems are usually fairly contrived, but they're also fairly standard. Keep in mind that the point of these exercises isn't their relation to "real life", but rather the growth of your ability to extract the mathematics from the English. These exercises are a great way to stretch your mental muscles, use what you know already, apply your logic (and common sense), and then hippity-hop your way to the answer.

## What is an example of solving a number word problem?

• The sum of two consecutive integers is 15 . Find the numbers.

They've given me many pieces of information here.

• I'm adding (that is, summing) two things
• the numbers are integers (like −3 and 6 )
• the second number is 1 more than the first
• the result of the addition will be 15

How do I know that the second number will be larger than the first by 1 ? Because the two integers are "consecutive", which means "one right after the other, not skipping over anything between". (Examples of consecutive integers would be −12 and −11 , 1 and 2 , and 99 and 100 .)

The "integers" are the number zero, the whole numbers, and the negatives of the whole numbers. In going from one integer to the next consecutive integer, I'll have gone up by one unit.

I need to figure out what are the two numbers that I'm adding. The second number is defined in terms of the first number, so I'll pick a variable to stand for this number that I don't yet know:

1st number: n

The second number is one more than the first, so my expression for the second number is:

2nd number: n + 1

I know that I'm supposed to add these two numbers, and that the result will be (in other words, I should set the sum equal to) 15 . This, along with my translation skills, allows me to create an equation, being the algebraic equivalent to "(this number) added to (the next number) is (fifteen)":

n + ( n + 1) = 15

This is a linear equation that I can solve :

2 n + 1 = 15

The exercise did not ask me for the value of the variable n ; it asked for the identity of two numbers. So my answer is not " n  = 7 "; the actual answer, taking into account the second number, too, is:

The numbers are 7 and 8 .

It usually isn't required that you write your answer out like this; sometimes a very minimal " 7, 8 " is regarded as acceptible form. But the exercise asked me, in complete sentences, a question about two numbers; I feel like it's good form to answer that question in the form of a complete sentence.

## What do they mean when they say "consecutive even (or odd) integers"?

Some number word problems will refer to "consecutive even (or odd) integers". This means that they're talking about two whole numbers (or their negatives) that are both even or else both odd; in particular, the two numbers are 2 units apart.

• The product of two consecutive negative even integers is 24 . Find the numbers.

• I'm multiplying (that is, finding the product of) two things
• those two things are numbers
• those two numbers are integers
• those two integers are even
• those two even integers are negative
• the second even integer is 2 units more than the first
• when I multiply, I'll get 24

How do I know that one number will be 2 more than the other? Because these numbers are consecutive even integers; the "consecutive" part means "the one right after the other", and the "even" part means that the numbers are two units apart. (Examples of consecutive even integers are 10 and 12 , −14 and −16 , and 0 and 2 .)

The second number is defined in terms of the first number, so I'll pick a variable for the first number. Then the second number will be two units more than this.

1st number: n 2nd number: n + 2

When I multiply these two numbers, I'm supposed to get 24 . This gives me my equation:

( n )( n + 2) = 24

This is a quadratic equation that I can solve :

( n )( n + 2) = 24 n 2 + 2 n = 24 n 2 + 2 n − 24 = 0 ( n + 6)( n − 4) = 0

This equation clearly has two solutions, being n  = −6 and n  = 4 . Since the numbers I am looking for are negative, I can ignore the " 4 " solution value and instead use the n  = −6 solution.

Then the next number, being larger than the first number by 2 , must be n  + 2 = −4 , and my answer is:

The numbers are −6 and −4 .

In the exercise above, one of the solutions to the exercise — namely, n  = −6 — was one of the solutions to the equation; the other solution to the equation — namely, n  = 4 — had the sign opposite to the other answer to the exercise.

You will encounter this pattern often in solving this type of word problem. However, do not assume that you can use both solutions if you just change the signs to be whatever you think they ought to be. While this often works, it does not always work, and it's sure to annoy your grader. Instead, throw out invalid results, and solve properly for the valid ones.

• Twice the larger of two numbers is three more than five times the smaller, and the sum of four times the larger and three times the smaller is 71 . What are the numbers?

The point of exercises like this is to give me practice in unwrapping and unwinding these words, somehow turning the words into algebraic expressions and equations. The point is in the setting-up and solving, not in the relative "reality" of the exercise. That said, how do I solve this? The best first step is to start labelling.

I need to find two numbers and, this time, they haven't given me any relationship between the two, like "two consecutive even integers". Since neither number is defined by the other, I'll need two letters to stand for the two unknowns. I'll need to remember to label the variables with their definitions.

the larger number:  x

the smaller number:  y

Now I can create expressions and then an equation for the first relationship they give me:

twice the larger:  2 x

three more than five times the smaller:  5 y + 3

relationship between ("is"):  2 x = 5 y + 3

And now for the other relationship they gave me:

four times the larger:  4 x

three times the smaller:  3 y

relationship between ("sum of"):  4 x + 3 y = 71

Now I have two equations in two variables:

2 x = 5 y + 3

4 x + 3 y = 71

I will solve, say, the first equation for x = :

x = (5/2) y + (3/2)

(There's no right or wrong in this choice; it's just what I happened to choose while I was writing up this page.)

Then I'll plug the right-hand side of this into the second equation in place of the x :

4[ (5/2) y + (3/2) ] + 3 y = 71

10 y + 6 + 3 y = 71

13 y + 6 = 71

y = 65/13 = 5

Now that I have the value for y , I can back-solve for x :

x = (5/2)(5) + (3/2)

x = (25/2) + (3/2)

x = 28/2 = 14

As always, I need to remember to answer the question that was actually asked. The solution here is not " x  = 14 ", but is instead the following:

larger number: 14

smaller number: 5

## What are the steps for solving "number" word problems?

The steps for solving "number" word problems are these:

• Read the exercise through once; don't try to start solving it before you even know what it says.
• Figure out what you know (for instance, are you adding or multiplying?).
• Figure out what you don't know; this will probably be the value(s) of number(s).
• Pick one or more useful variables for unknown(s) that you need to find.
• Use the variable(s) and the known information to create expressions.
• Use these expressions and the known information to create one or more equations.
• Solve the equation(s) for the unknown(s).

But more than any list, the trick to doing this type of problem is to label everything very explicitly. Until you become used to doing these, do not attempt to keep track of things in your head. Do as I did in this last example: clearly label every single step; make your meaning clear not only to the grader but to yourself. When you do this, these problems generally work out rather easily.

## Directions for AlphaMath Problems (Problems 38 – 41):

• Letters stand for digits 0–9.
• In a given problem, the same letter always represents the same digit, and different letters always represent different digits.
• There is no relation between problems (so “A” in part 1 and “A” in part 3 might be different).
• Two, three, and four digit numbers never start with a zero.
• Your job: Figure out what digit each letter stands for, so that the calculation shown is correct.

Notes: In part 2, “O” represents the letter “oh,” not the digit zero.

• $$\begin{split} A & \\ A & \\ +\; A & \\ \hline H\; A & \end{split}$$
• $$\begin{split} O\; N\; E & \\ +\; O\; N\; E & \\ \hline T\; W\; O & \end{split}$$
• $$\begin{split} A\; B\; C & \\ +\; A\; C\; B & \\ \hline C\; B\; A & \end{split}$$

Here’s another AlphaMath problem. $\begin{split} T\; E\; N & \\ +\; N\; O\; T & \\ \hline N\; I\; N\; E & \end{split} \nonumber$

• Solve this AlphaMath problem in base 10.
• Now solve it in base 6.

Find all solutions to this AlphaMath problem in base 9 .

Notes: Even though this is two calculations, it is a single problem . All T’s in both calculations represent the same digit, all B’s represent the same digit, and so on.

Remember that “O” represents the letter “oh” and not the digit zero, and that two and three digit numbers never start with the digit zero

$\begin{split} T\; O & \\ -\; B\; E & \\ \hline O\; R & \end{split} \qquad \begin{split} N\; O\; T & \\ -\; T\; O & \\ \hline B\; E & \end{split} \nonumber$

This is a single AlphaMath problem. (So all G’s represent the same digit. All A’s represent the same digit. And so on.)

Solve the problem in base 6 . $GALON = (GOO)^{2} \qquad \qquad ALONG = (OOG)^{2} \nonumber$

• Which of the following base seven numbers are perfect squares? For each number, answer yes (it is a perfect square) or no (it is not a perfect square) and give a justification of your answer. $$4_{seven} \qquad 25_{seven} \qquad 51_{seven}$$

Geoff spilled coffee on his homework. The answers were correct. Can you determine the missing digits and the bases?

• Rewrite each subtraction problem as an addition problem: $$x - 156 = 279 \qquad 279 - 156 = x \qquad a - x = b \ldotp$$
• Rewrite each division problem as a multiplication problem: $$24 \div x = 12 \qquad x \div 3 = 27 \qquad a \div b = x \ldotp$$

Which of the following models represent the same multiplication problem? Explain your answer.

Show an area model for each of these multiplication problems. Write down the standard computation next to the area model and see how it compares. $20 \times 33 \qquad 24 \times 13 \qquad 17 \times 11 \nonumber$

Suppose the 2 key on your calculator is broken. How could you still use the calculator compute these products? Think about what properties of multiplication might be helpful. (Write out the calculation you would do on the calculator, not just the answer.) $1592 \times 3344 \qquad 2008 \times 999 \qquad 655 \times 525 \nonumber$

Today is Jennifer’s birthday, and she’s twice as old as her brother. When will she be twice as old as him again? Choose the best answer and justify your choice.

• Jennifer will always be twice as old as her brother.
• It will happen every two years.
• It depends on Jennifer’s age.
• It will happen when Jennifer is twice as old as she is now.
• It will never happen again.
• Find the quotient and remainder for each problem. $$7 \div 3 \qquad 3 \div 7 \qquad 7 \div 1 \qquad 1 \div 7$$
• How many possible remainders are there when dividing by these numbers? Justify what you say. $$2 \qquad 12 \qquad 62 \qquad 23$$

Identify each problem as either partitive or quotative division and say why you made that choice. Then solve the problem.

• Adriana bought 12 gallons of paint. If each room requires three gallons of paint, how many rooms can she paint?
• Chris baked 15 muffins for his family of five. How many muffins does each person get?
• Prof. Davidson gave three straws to each student for an activity. She used 51 straws. How many students are in her class?

Use the digits 1 through 9. Use each digit exactly once. Fill in the squares to make all of the equations true. $\begin{split} \Box - \Box = \Box & \\ \times & \\ \Box \div \Box = \Box & \\ = & \\ \Box + \Box = \Box & \end{split} \nonumber$

## Solving for Two or More Numbers

Some number word problems ask you to find two or more numbers. It may be tempting to name them all with different variables, but so far we have only solved equations with one variable. We will define the numbers in terms of the same variable. Be sure to read the problem carefully to discover how all the numbers relate to each other.

One number is five more than another. The sum of the numbers is twenty-one. Find the numbers.

Watch the following video to see another example of how to find two numbers given the relationship between the two.

The sum of two numbers is negative fourteen. One number is four less than the other. Find the numbers.

One number is ten more than twice another. Their sum is one. Find the numbers.

## Solving for Consecutive Integers

Consecutive integers are integers that immediately follow each other. Some examples of consecutive integers are:

$\begin{array}{c}\phantom{\rule{0.2em}{0ex}}\\ \phantom{\rule{0.2em}{0ex}}\\ \phantom{\rule{0.2em}{0ex}}\\ \phantom{\rule{0.2em}{0ex}}\\ \hfill \text{…}1,2,3,4\text{,…}\hfill \end{array}$ $\text{…}-10,-9,-8,-7\text{,…}$ $\text{…}150,151,152,153\text{,…}$

Notice that each number is one more than the number preceding it. So if we define the first integer as $n$, the next consecutive integer is $n+1$. The one after that is one more than $n+1$, so it is $n+1+1$, or $n+2$.

$\begin{array}{cccc}n\hfill & & & \text{1st integer}\hfill \\ n+1\hfill & & & \text{2nd consecutive integer}\hfill \\ n+2\hfill & & & \text{3rd consecutive integer}\hfill \end{array}$

The sum of two consecutive integers is $47$. Find the numbers.

Find three consecutive integers whose sum is $42$.

Watch this video for another example of how to find three consecutive integers given their sum.

## 3.7 Numeric Word Problems

Number-based word problems can be very confusing, and it takes practice to convert a word-based sentence into a mathematical equation. The best strategy to solve these problems is to identify keywords that can be pulled out of a sentence and use them to set up an algebraic equation.

Variables that are to be solved for are often written as “a number,” “an unknown,” or “a value.”

“Equal” is generally represented by the words “is,” “was,” “will be,” or “are.”

Addition is often stated as “more than,” “the sum of,” “added to,” “increased by,” “plus,” “all,” or “total.” Addition statements are quite often written backwards. An example of this is “three more than an unknown number,” which is written as $x + 3.$

Subtraction is often written as “less than,” “minus,” “decreased by,” “reduced by,” “subtracted from,” or “the difference of.” Subtraction statements are quite often written backwards. An example of this is “three less than an unknown number,” which is written as $x - 3.$

Multiplication can be seen in written problems with the words “times,” “the product of,” or “multiplied by.”

Division is generally found by a statement such as “divided by,” “the quotient of,” or “per.”

Example 3.7.1

28 less than five times a certain number is 232. What is the number?

• 28 less means that it is subtracted from the unknown number (write this as −28)
• five times an unknown number is written as $5x$
• is 232 means it equals 232 (write this as = 232)

Putting these pieces together and solving gives:

$\begin{array}{rrrrrr} 5x&-&28&=&232& \\ &+&28&&+28& \\ \hline &&5x&=&260& \\ \\ &&x&=&\dfrac{260}{5}&\text{or }52 \end{array}$

Example 3.7.2

Fifteen more than three times a number is the same as nine less than six times the number. What is the number?

• Fifteen more than three times a number is $3x + 15$ or $15 + 3x$
• nine less than six times the number is $6x-9$

Putting these parts together gives:

$\begin{array}{rrrrrrr} 3x&+&15&=&6x&-&9 \\ -6x&-&15&=&-6x&-&15 \\ \hline &&-3x&=&-24&& \\ \\ &&x&=&\dfrac{-24}{-3}&\text{or }8& \\ \end{array}$

Another type of number problem involves consecutive integers, consecutive odd integers, or consecutive even integers. Consecutive integers are numbers that come one after the other, such as 3, 4, 5, 6, 7. The equation that relates consecutive integers is:

$x, x + 1, x + 2, x + 3, x + 4$

Consecutive odd integers and consecutive even integers both share the same equation, since every second number must be skipped to remain either odd (such as 3, 5, 7, 9) or even (2, 4, 6, 8). The equation that is used to represent consecutive odd or even integers is:

$x, x + 2, x + 4, x + 6, x + 8$

Example 3.7.3

The sum of three consecutive integers is 93. What are the integers?

The relationships described in equation form are as follows:

$x + x + 1 + x + 2 = 93$

Which reduces to:

$\begin{array}{rrrrrr} 3x&+&3&=&93& \\ &-&3&&-3& \\ \hline &&3x&=&90& \\ \\ &&x&=&\dfrac{90}{3}&\text{or }30 \\ \end{array}$

This means that the three consecutive integers are 30, 31, and 32.

Example 3.7.4

The sum of three consecutive even integers is 246. What are the integers?

$x + x + 2 + x + 4 = 246$

$\begin{array}{rrrrrr} 3x&+&6&=&246& \\ &-&6&&-6& \\ \hline &&3x&=&240& \\ \\ &&x&=&\dfrac{240}{3}&\text{ or }80 \\ \end{array}$

This means that the three consecutive even integers are 80, 82, and 84.

For questions 1 to 8, write the formula defining each relationship. Do not solve.

• Five more than twice an unknown number is 25.
• Twelve more than 4 times an unknown number is 36.
• Three times an unknown number decreased by 8 is 22.
• Six times an unknown number less 8 is 22.
• When an unknown number is decreased by 8, the difference is half the unknown number.
• When an unknown number is decreased by 4, the difference is half the unknown number.
• The sum of three consecutive integers is 21.
• The sum of the first two of three odd consecutive integers, less the third, is 5.

For questions 9 to 16, write and solve the equation describing each relationship.

• When five is added to three times a certain number, the result is 17. What is the number?
• If five is subtracted from three times a certain number, the result is 10. What is the number?
• Sixty more than nine times a number is the same as two less than ten times the number. What is the number?
• Eleven less than seven times a number is five more than six times the number. Find the number.
• The sum of three consecutive integers is 108. What are the integers?
• The sum of three consecutive integers is −126. What are the integers?
• Find three consecutive integers such that the sum of the first, twice the second, and three times the third is −76.
• Find three consecutive odd integers such that the sum of the first, two times the second, and three times the third is 70.
