4. Реши: 116 * 6 436 + 280 90 + 854 420 - 120 : 3 492 * 2 725 + 175 612 - 97 280 + 60 * 2 345 * 2 354 + 96 50 + 124 84 : 12 * 7

Решение:

$$116 \cdot 6 = 696$$

$$436 + 280 = 716$$

$$90 + 854 = 944$$

$$420 - 120 : 3 = 420 - 40 = 380$$

$$492 \cdot 2 = 984$$

$$725 + 175 = 900$$

$$612 - 97 = 515$$

$$280 + 60 \cdot 2 = 280 + 120 = 400$$

$$345 \cdot 2 = 690$$

$$354 + 96 = 450$$

$$50 + 124 = 174$$

$$84 : 12 \cdot 7 = 7 \cdot 7 = 49$$

Ответ: 696, 716, 944, 380, 984, 900, 515, 400, 690, 450, 174, 49
