Explicație pas cu pas:
8 × 4 + 18 = 32 + 18 = 50
45 + 9 : 3 = 45 + 3 = 48
28 - 4 × 7 = 28 - 28 = 0
___________________________________________
27 : 9 + 21 : 3 = 3 + 7 = 10
15 + 5 × 5 + 10 = 15 + 25 + 10 = 50
72 : 8 - 45 : 9 = 9 - 5 = 4
___________________________
5 × 5 + 5 × 5 + 5 = 25 + 25 + 5 = 55
5 : 5 + 5 : 5 + 5 = 1 + 1 + 5 = 7
5 × 5 + 5 + 5 : 5 = 25 + 5 + 1 = 31
