4 + (-3) = 1 Here is what adding integers means. -1 1 2 3 4 5

-2 + (-3) = -5 -5 -4 -3 -2 -1 1

2 – 3 = -1 Here is what adding integers means. -1 1 2 3 4 5

You can change all problems to ADDING! 1) Normal looking problem 2 - 3 Same Change Change 2 +(-3) = - 1 Same Change Change Then follow addition rules!

-2 - 3 = -5 -5 -4 -3 -2 -1 1

You can change all problems to ADDING! 2) Same Signs -2 - 3 Same Change Change -2 +(-3) = - 5 Same Change Change Then follow addition rules!

2 – (-3) = 5 Here is what adding integers means. -1 1 2 3 4 5

You can change all problems to ADDING! 3) Double Negatives 2 – (-3) When 2 negatives are next to each other they BOTH become positives!!! 2 + (+3) = 5 Same Change Change Then follow addition rules!

-2 – (-3) = 1 -5 -4 -3 -2 -1 1

You can change all problems to ADDING! 4) ALL Negatives -2 – (-3) ONLY the 2 negatives next to each other change! -2 + (+3) = 1 Same Change Change Then follow addition rules!

Lets Practice 5 – 7 -9 – (-4) -1 – 5 5 + (-7) -9 + (+4) -1 + (-5) -2 -6 8 – 3 -6 – 2 3 – (-7) 5 -6 + (-2) 3 + (+7) -8 10

Watch for multi-step problems -4 – (-7) – 8 9 – (-4) – (-3) 3 – 8 13 – 8 5 -5
