1) To work out 3 x 3 we need to remember what multiply means. When we multiply 3 by 3 we have three lots of 3. So

3 x 3 = 3 + 3 + 3 = 9

2) Similarly when we multiply 3 by 5 we have five lots of 3. So

3 x 5 = 3 + 3 + 3 + 3 + 3 = 15

We can also think of this as three lots of 5, so that

3 x 5 = 5 + 5 + 5 = 15

1) 3 x 3 = 3 + 3 + 3 = 9

2) 3 x 5 = 3 + 3 + 3 + 3 + 3 = 5 + 5 + 5 = 15

 3 x 3 equal? What does 3 x 5

3xx3 = 3+3+3   

`3+3=6+3=9 `  so `3xx3=9`

`3xx5=3+3+3+3+3`

`3+3=6+3=9+3=12+3=15 `  so `3xx5=15`
