Section 1.6 Subtracting Integers Algebra Concepts Section 1.6 Subtracting Integers

We will NEVER do subtraction problems!!!!! All subtraction problems will be changed to addition!!!!

For each problem, #1 put each integer in parentheses #2 there is a subtraction sign between the two sets of parentheses-change it to an addition sign #3 change the second number to its opposite #4 use the rules for adding!

Parentheses-keep-add a line -opposite 6−8 6 − 8 6 + −8 −2

A little jingle! Dress numbers up to look mighty fine. Keep, add a line, change the sign.

−8 − −2 −8 + +2 −6

Try these! #1 100− −40 #2 −60−10 #3 −32−12 #4 16−12 #5 25−7
