Answer 2

1)56×1+66:6=56+11=67
2) 13×(4+2):1=13×6:1=78
3)77×0+25×3=0+25×3=0+75=75
4)(27+13)×2-78=40×2-78=80-78=2
5)39:(7+6)×21=39:13×21=3×21=63
6)81-68:(9+8)=81-68:17=81-4=77
7)(45+15):15+76=60:15+76=4+76=80
8)80:20×(48-48)=0
9)20×3-(56+0)=20×3-56=60-56=4

Answer 3

56*1 = 56 66:6 = 11 13*(4+2) = 78 77*0 = 0 25*3 = 75 (27+13)*2-78 = 52 39:(7+6)*21 = 3 81-68:(9+8) = 77 (45+15):15+76 = 79 80:20*(48-48) = 0 20*3-(56+0) = 60 - 56 = 4

Итак, результаты вычислений: 56*1+66:6 = 56 + 11 = 67 13*(4+2):1 = 78:1 = 78 77*0+25*3 = 0 + 75 = 75 (27+13)*2-78 = 52 39:(7+6)*21 = 3 81-68:(9+8) = 77 (45+15):15+76 = 79 80:20*(48-48) = 0 20*3-(56+0) = 4
