Determine the integer whose product with (-1) is

(a) – 22

(b) 37

(c) 0

Verify the following:

(a) 18 ×[7+(-3)] = [18 × 7] + [18 × (-3)]

(b) (-21) ×[(-4)+(-6)] = [(-21) ×(-4)] + [(-21) ×(-6)]

For any integer a, what is (-1) × a equal to?

Starting from (-1) × 5, write various products showing some pattern to show (-1) ×(-1)=1

Find the product, using suitable properties:

(a) 26 × (– 48) + (– 48) × (–36)

(b) 8 × 53 × (–125)

(c) 15 × (–25) × (– 4) × (–10)

(d) (– 41) × 102

(e) 625 × (–35) + (– 625) × 65

(f) 7 × (50 – 2)

(g) (–17) × (–29)

(h) (–57) × (–19) + 57
