- helpful tricks for factoring numbers:
  - If a number is even (un par en espanol), then it is evenly divisible by 2.
  - If the sum of the digits of a number is a multiple of 3, then it is evenly divisible by 3.
  - If the sum of the digits of a number is a multiple of 3 and the number is even, then it is evenly divisible by 6.
  - If the last digit in a number is either 5 or 10, then it is is evenly divisible by 5.
  - If the sum of the digits of a number is a multiple of 9, then it is evenly divisible by 9.
- Techniques for mental math operations
