Part two

Use Integers in Applications

Use Integers in Applications

We’ll outline a plan to solve applications. It’s hard to find something if we don’t know what we’re looking for or what to call it! So when we solve an application, we first need to determine what the problem is asking us to find. Then we’ll write a phrase that gives the information to find it. We’ll translate the phrase into an expression and then simplify the expression to get the answer. Finally, we summarize the answer in a sentence to make sure it makes sense.

Example 1: How to Apply a Strategy to Solve Applications with Integers

Question:

The temperature in Urbana, Illinois, one morning was

11
 degrees. By mid-afternoon, the temperature had dropped to

−9
 degrees. What was the difference of the morning and afternoon temperatures?

Solution:

Step 1. Read the problem. Make sure all the words and ideas are understood.

Step 2. Identify what we are asked to find.

the difference of the morning and afternoon temperatures

Step 3. Write a phrase that gives the information to find it.

the difference of

11
 and

−9

Step 4. Translate the phrase to an expression.



11−(−9)

Step 5. Simplify the expression.



20

Step 6. Write a complete sentence that answers the question.

The difference in temperatures was

20
 degrees.
