2. Calculează:
a) 2 x 7 =
3 x 2 =
8 x 2 =
2 x 9 =
4 x 2 =
b) (3 + 2) x 2 =
2 x (4 + 2) =
(2 + 5) x 2 =
2 x (7 + 2) =
(8 + 2) x 2 =
c) 3 x 2 x 2 =
2 x 4 x 2 =
2 x 2 x 2 =
5x 2 x 2 =
4 x 2 x 2 =

Answer 1

1. 6x2=12

2x4=8

8x2=16

2x9=18

5x2=10

2. a) 2x7=14

3x2=6

8 x 2 = 16

2 x 9 = 18

4 x 2 = 8

b) (3 + 2) x 2 = 5x2=10

2 x (4 + 2) = 2x6=12

(2 + 5) x 2 = 7x2=14

2 x (7 + 2) = 2x9=18

(8 + 2) x 2 =10x2=20

c) 3 x 2 x 2 = 12

2 x 4 x 2 =16

2 x 2 x 2 = 6

5x 2 x 2 = 20

4 x 2 x 2 =16
