Our shared thinking about integers
Multiplying Integers
* if 4 x 2 = 8 then 4 x -2 = -8
3 x -3 = -9
2 x -4 = -8
if the second factor is a negative then the answer is negative (Devon)
2 x - 5 = -10
if the first factor is negative then the answer is negative (Jonathan)
-2 x 5 = -10
if there are 2 negatives then the answer is positive (Jack)
-2 x -5 = 10
