Question

Calculează respectând ordinea efectuării operațiilor

Answer 1

25 : 5 + 79 = 5 + 79 = 84
30 : 5 - 6 = 6 - 6 = 0
84 + 40 : 5 = 84 + 8 = 92
70 - 20 : 5 = 70 - 4 = 66
40 : 5 × 9 - 38 = 8 × 9 - 38 = 72 - 38 = 34
19 + 27 : 3 × 7 = 19 + 9 × 7 = 19 + 63 = 82
100 - 19 - 45 : 9 = 100 - 19 - 5 = 81 - 5 = 76
