Using Duplication and Mediation...
Calculate 9 x 7
Divide the left hand column by 2
If it is odd, go to the next lowest integer.
Double Column 2
Cross out right hand column values with even left hand values
| 7 | 9 |
|---|---|
| 7 ÷ 2 = 3 | 9 x 2 = 18 |
| 3 ÷ 2 = 1 | 18 x 2 = 36 |
Now that Column 1 is equal to 1...
Add up all right hand columns with odd left hand columns:
9 + 18 + 36 = 63
Therefore, 9 x 7 = 63
63
