Introduction to Subtracting Integers

A photo of the Chicago skyline during a freezing, snowy winter What's the difference between the temperature in Chicago and the temperature in Los Angeles?
Do you ever compare the weather where you are with the weather where your friends or family members live? Imagine that it's winter, and you call your parents in Chicago from your house in Los Angeles, where the temperature is [latex]65[/latex] degrees. They tell you that the temperature in Chicago, where you grew up, is [latex]-2[/latex] degrees. What's the difference in temperature between the two cities? To find out, you'll need to subtract integers, which you'll learn how to do in this section.  

Learning Outcomes

By the end of this section, you will be able to:
  • Model subtraction of integers
  • Simplify expressions with integers
  • Evaluate variable expressions with integers
  • Translate words phrases to algebraic expressions
  • Subtract integers in applications
  Before you get started in this module, try a few practice problems and review prior concepts.
