1. Subtracting Integers I Love Numbers!!!

2. Quick Review of Adding Integers Adding Rule #1 – If the signs are the same, add as you normally do. – Keep the same sign. 5 + 8 = -8 + -17 = Adding Rule #2 – If the signs are DIFFERENT, pretend the signs aren’t there. – Subtract the smaller from the larger one. – Keep the sign of the number with the GREATEST Absolute Value. 19 + -11 = 24 + -86 = 13 -25 8 -62

3. 3 Steps to Subtract Integers Keep – Keep the 1 st number Change – Subtraction sign to Addition Opposite – Write down the opposite of the 2 nd number Then add the way you normally do.

4. -9 – 14 = Keep Change Opposite -9-14 - = Now follow the adding integers rules. -23

5. Practice… 1.-7 – 15 = 2.23 – 98 = 3.-48 - - 13 = 4.5 - - 6 = 5.17 – 8 = -22 -75 -35 11 9
