Math 2 - Math Facts and Patterns

A good mathematician looks for patterns. In our first few classes we discovered the following math patterns and facts.

1. Any number times 0 equals 0. (Example: 3 x 0 = 0)
2. Any number times 1 equals that number. (Example 15 x 1 = 15)
3. Any number times 10 always ends in 0.
4. Any number times 5 always ends in 5 or 0.
5. Even numbers end in 0, 2, 4, 6, or 8.
6. Odd numbers end in 1, 3, 5, 7, or 9.
7. An even number times an even number always equals an even number.
8. An odd number times an even number always equals an even number.
9. An odd number times an odd number always equals an odd number.
