Solving a promblem

Walt: Use more than one strategy to solve multiplication number problems


This is the problem that I'd solved with these strategies.
The first strategies that I used is repeated addition:
9+9+9+9+9+9+9=63

The second strategies that I used is place value:
9x7=63
5x7=35
4x7=28
35+28=63
