Решить примеры8*5-(60-42): 3+9*2, 5*7+(18+14): 4-(26-8): 3*2,(58-31): 3-2+(58-16): 6, (9*7+56: *6-4)*3+54: 9.

1) = 40 - (18 : 3)+ 18 = 40 - 6 + 18 = 52
2) = 35 + (32 : 4) - (18 : 3 * 2) = 35 + 8 - 12 = 31
3) = 27 : 3 - 2 + 42 : 6 = 9 - 2 + 7 = 14
4) = (63 + 8) - (12 -4)*3 + 6 = 71 - 8*3 + 6 = 71 - 24 + 6 = 53
