Question

Analiza si conviene aplicar la ley distributiva o no y calcula:

(a) 13 × (17 + 14 – 30) (b) (11 + 12 + 35) × 10 (c) (1 + 2 – 3 + 4) × 4
​

Answer 1

Si que conviene aplicarla porque hay paréntesis.

(a) 13 × (17 + 14 – 30) = 13 x (31-30) = 13 x 1 = 13

(b) (11 + 12 + 35) × 10 = (23+35) x 10 = 58 x 10 = 580

(c) (1 + 2 – 3 + 4) × 4 = (3-3+4) x 4 = 4 x 4 = 16
