6 x 998 = (a) (6 x 1000) – (6 x 2) = 6000 – 12 = 5988 ✔

(b) (6 x 99) + (6 x 8) = 600 + 48 = 648

(c) (6 x 900) + (6 x 90) + (6 x 8) = 5400 + 540 + 48 = 6000

76 ÷ 4 = (a) (70 x 6) – (6 x 4) = 420 – 24 = 396

(b) (80 ÷4) – (4 ÷ 4) = 20 – 1 = 19       ✔

(c) (70 ÷ 4) – (6 ÷ 4) = 764

28 x 5 = (a) (28 x 10) – (8 x 5) = 280 – 40 = 240

(b) (2 x 5) + (8 x 5) = 10 + 40 = 50

(c) (20 x 5) + (8 x 5) = 100 + 40 = 140  ✔

96 ÷ 6 = (a) 6 x 16 ✔ (b) 6 x 96 (c) 9 x 6       

24 x 5 = (a) 12 x 10 = 120   ✔ (b) 48 x 10 = 480 (c) 48 x 5
