1.) 2, 3, 5, 8, 12…
- 2 + 1 = 3
- 3 + 2 = 5
- 5 + 3 = 8
- 8 + 4 = 12
2.) 4, 9, 14, 19, 24
- 4 + 5 = 9
- 9 + 5 = 14
- 14 + 5 = 19
- 19 + 5 = 24
3.) 9, 14, 27, 26, 45
- 9 x 1 = 9
- 9 x 2 = 14
- 9 x 3 = 27
- 9 x 4 = 36
- 9 x 5 = 45
4.) 11, 22, 33, 44, 55…
- 11 x 1 = 11
- 11 x 2 = 22
- 11 x 3 = 33
- 11 x 4 = 44
- 11 x 5 = 55
5.) 4, 6, 10, 16, 24
- 4 + 2 = 6
- 6 + 4 = 10
- 10 + 6 = 16
- 16 + 8 = 24
6.) 5 x 8 = 8 x 5
- 5 x 8 = 40
- 8 x 5 = 40
- Multiplication is commutative, if you interchange the factors the product doesn't change.
7.) (4 x 5) x 3 = 4 x (5 x 3)
- (4 x 5) x 3 = 60
- 4 x (5 x 3) = 60
- Multiplication is commutative, changing the place of the parenthesis doesn't change the product.
8.) (12 + 8) + 9 = 12 + (8 + 9)
- (12 + 8) + 9 = 29
- 12 + (8 + 9) = 29
- Addition is also commutative, changing the place of the parenthesis doesn't change the sum.
9.) 45 + 11 = 11 + 45
- 45 + 11 = 56
- 11 + 45 = 56
- Addition is commutative, if you interchange the addends the sum will not change.
10.) 28 + 0 = 28
