Malachi's Math Strategy!

Malachi learnt new ways to solve equations in maths. This is the Strategy that he used to solve the problems.

6 x 18 = 10

10+8  10+8  10+8

10+8  10+8  10+8

6 x 8 = 48  

6 x 10 = 60

48 + 60 = 108

4 x 34 = 136

30 + 4  30 + 4  

30 + 4  30 + 4

4 x 4 = 16

4 x 30 = 120  

16 + 120 = 136

7 x 23 = 161

20 + 3 20 + 3 20 + 3

20 + 3 20 + 3 20 + 3

20 + 3

7 x 3 = 21

7 x 20 = 140

140 + 21 = 161
