10:00am Math: multiplication of negative integers
2 × 3 2 × (-3) (-2) × (-3)
= 6 = –6 = 6
[one positive, one negative = negative] [two negatives = positive]
Same thing for division
21 ÷ 3 = 7 (–21) ÷ 3 = –7 (–21) ÷ (–3) = 7
Try these questions
12 × 13 (–12) × 13 (–12) × (–13) 12 × (–13)
1527 ÷ 3 (–1527) ÷ 3 1527 ÷ (–3) (–1527) ÷ (–3)
Now. the questions below have three or four steps. Calculate the answers. . . Will the answers be positive or negative?
12 × 13 ÷ (–2) (–12) × 13 ÷ (–2) (–12) × (–13) ÷ (–2)
(–12) × (–13) ÷ 2 12 × 13 ÷ 2
20 × 15 ÷ (–4) (–20) × 15 ÷ (–4) (–20) × (–15) ÷ (–4)
(–20) × (–15) ÷ 4 20 × 15 ÷ 4
Next part will involve the exponents
32 = 3 × 3 = 9 (–3)2 = (–3) × (–3) = 9 (the answer is positive because two negatives turn into a positive answer)
(–3)3 = (–3) × (–3) × (–3)= (–27) (the answer is negative because two negatives turn into a positive answer, then multiply by a negative turns into –)
72 (–7)2 (–7)3 (-7)5 (–7)6
