Fill them out below: (a) ___ × (___ + ___) = 14 (b) ___ × (___ + ___) = 14 (c) ___ × (___ + ___) = 14 (d) ___ × (___ + ___) = 14 Since 14 = 14 × 1 And 14 = 7 × 2 We try to make either 14 × 1, 1 × 14, or 7 × 2, 2 × 7 Thus, we could do 1 × (6 + 8) = 14 2 × (3 + 4) = 14 7 × (1 + 1) = 14 14 × (0 + 1) = 14
