- Multiplication (often denoted by the cross symbol "×") is the mathematical operation of scaling one number by another.
- Whole-number products greater than 1 can be computed by repeated addition;

**for example:**

- 7 multiplied by 3 (often said as "7 times 3") can be calculated by adding 7 copies of 3 together: 7 x 3 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21
- Here 7 and 3 are the "factors" and 21 is the "product".
- 7 multiplied by 3 can also be calculated by adding 3 copies of 7 together: 7 x 3 = 7 + 7 + 7 = 21
