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
