Title: x and ÷ Integers

VOCABULARY 1. integers—the set of numbers containing positive and negative whole numbers and sign—refers to the property of being positive or negative. 3. undefined—has no real meaning

4. When multiplying or dividing integers, an even # of negative signs means the answer is positive (0,2,4,6) An odd # of negative signs makes the answer negative (1,3,5).

4 x -8 = x -8 = 64 (-48)÷ 6 = ˉ8 2 x 2 x ˉ2 x (ˉ2) = 16

5. A 0 will make the answer 0 unless you are dividing by 0 which is undefined. -4 x 0 = 0 0 ÷ 8 = 0 4 ÷ 0 is undefined.

EX--- ˉ7 x ˉ9 = ˉ 72 ÷ 8 = 3 x 3 x (ˉ2) = 0 ÷ 23 = 5 x ˉ3 x ˉ2 = ˉ6 ÷ 0 =
