Explicație pas cu pas:

2 x (3+2) = 2 x 6 = 12

5 x (1+1) = 5 x 2 = 10

2 x (4+0) =2 x 4 = 8

4 x (8-6) = 4 x 2 = 8

8 x 2 + 10 = 16 + 10 = 26

2 x 9 + 4 = 18 + 4 = 22

7 x 2 - 5 = 14 - 5 = 9

2 x 6 - 6 = 12 - 6 = 6

(25-20) x 2 = 5 x 2 = 10

(40-30) x 2 = 10 x 2 = 20

(5+3) x 2 = 8 x 2 = 16

(6+3) x 2 = 9 x 2  = 18
