Question

определи порядок действий и найди значения выражений. 37+12:6. 5×2+4:2. 450+6:3. 27+6-3. 54-14-7. 540-40+7. 12:6×3. 18:9×5. 8×3:4. (6+10):2+5. 50+(98-90)×2. 850-(2×6+12)

Answer 1

37 + 12 : 6 = 37 + 2 = 39

5 * 2 + 4 : 2 = 10 + 4 : 2 = 10 + 2 = 12

450 + 6 : 3 = 450 + 2 = 452

27 + 6 - 3 = 33 - 3 = 30

54 - 14 - 7 = 40 - 7 = 33

540 - 40 + 7 = 500 + 7 = 507

12 : 6 * 3 = 2 * 3 = 6

18 : 9 * 5 = 2 * 5 = 10

8 * 3 : 4 = 24 : 4 = 6

(6 + 10) : 2 + 5 = 16 : 2 + 5 = 8 + 5 = 13

50 + (98 - 90) * 2 = 50 + 8 * 2 = 50 + 16 = 66

850 - (2 * 6 + 12) = 850 - (12 + 12) = 850 - 24 = 826
