1. Adding Integers

2. We work DOWN, not across.

3. Additive Inverse any 2 numbers whose sum is zero opposites are additive inverses

4. What is a sum? the answer to an addition problem sum

5. The additive inverse of…… 4 is … 9 is … -61 is … -367 is … -4593 is … 7 / 9

6. Adding Numbers with the Same Sign Add the numbers and keep the sign. Ex. 1) 5 + 37 Ex. 2) (-62) + (-13)

7. Adding Numbers with Different Signs To add numbers with different signs, simply find the difference between the numbers and use the sign of the number further from 0 (the difference is the answer to a subtraction problem)

8. Adding with Different Signs Ex. 3) 6 + (-4) zero pairs

9. Adding with Different Signs -14 + 10 10 + (-14) 14 – 10 - 4

10. Practice (Same signs—add & keep)

11. More Practice **Different signs

12. Same signs add and keep, different signs subtract. Keep the sign of the further number, then you’ll be exact. (to the tune of Row, Row, Row Your Boat)
