Repeated Addition (2)

Multiplication as repeated addition

REMEMBER : 
5 + 5 + 5 = 3 x 5 = 15

Example : 

1.   2 + 2 + 2                     = 2 x 3 = 6

2.   5 + 5                           = 5 x 2 = 10

3.   1 + 1 + 1 + 1 + 1 + 1  = 1 x 6 = 6 

4.   3 lots of 10                = 10 x 3 = 30

5.   10 lots of 5                = 5 x 10 = 50

6.   7 lots of 2                  = 2 x 7 = 14

7.   3 + 3 + 3 + 3 + 3        = 5 lots of 3 = 15

8.   2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 8 lots of 2 = 16

9.   4 lots of 10                = 4 x 10 = 40
