Explicație pas cu pas:

1.

=56: (100-40-30-21-1)

=56:8

=7

2.

=(24+12):4 + 7 - (28-4) :6

=36:4 + 7 - 24:6

=9+7-4

=12

3.

=(9×3-12):3

=(27-12):3

=15:3

=5

4.

=30+4+56-10

=90-10

=80

5.

=20-(15-2+3) : (26-18)

=20-16:8

=20-2

=18

6.

=40:5×3+32-4×7

=8×3+32-32-28

=24+32-32-28

=24-28

=-4

7.

=(72-8)-(91-91)

=64-0

=64

8.

=100-(27+42-6):7

=100-(69-6):7

=100-63:7

=100-9

=91

9.

=(32+27+21):10:(40-36)

=(59+21):10:4

=80:10:4

=8:4

=2
