Integers Multiplication and Division

Integer multiplication operation sign and division operation sign follow the same rules:

1) Like signs are positive (+5) x (+6) = (+30) or 30 and

(- 55) ÷ ( - 5) = (+11) or 11

2) Unlike signs are negative (+12) ÷ (- 4) = (- 3) and

(+7) x (- 4) = (- 28)

A scrap box should be used to do the calculations. Try not to get into the habit of doing your scrap work on another piece of paper. It is much easier to find a mistake if all the work is in front of you and located close to the problem.
