Problem of the Week

This week's problem solving strategy has been on finding patterns.

Find the Pattern:

3 * 4 --> 5
4 * 7 --> 1
8 * 4 --> 0
1 * 2 --> 9

The challenge is to discover how the third number is obtained from the first two numbers. If you know the pattern, then you will be able to complete these statements:

5 * 5 --> ?
4 * 1 --> ?
6 * 2 --> ?
