Integers 7th Grade Math

Integers Integers are whole numbers and their opposites. This means they are positive and negative numbers. Examples: - 4, 5, -5, 2, -245

Comparing Integers When you compare integers, you need to place them on a number line and then decide the order they go in. The further right a number is on the number line the larger it is.

**Add and Subtract Song to the tune of “Row Row Row Your Boat”**

Same Signs Add and Keep Different Signs, Subtract Keep the sign of the larger value Then you will be exact *It works!!!

5
**Practice - 3 + - 6 = Same signs – add**

answer is negative because 6 is larger 8 + (- 4) = Different signs- subtract 8-4= 4 and the answer is positive because 8 is larger

One Exception If you have a subtraction sign with a negative sign right next to it…. Then you will change them to a plus sign and then follow the rules to the song. 6 – (- 3) = 6 + 3 = 9

7
**Multiply and Divide Rules for multiplication and division…**

Same signs = positive answer Different signs = negative answer + x + = + + / + = + - x - = + - / - = + + x - = / - = - - x + = / + = -
