- Multiplication is a mathematical operation that represents the repeated addition of a number
- It is denoted by the multiplication symbol × (or *)
- The result of multiplication is called the product
Properties
-
Commutative Property: The order of the numbers being multiplied does not change the product
- Example: 2 × 3 = 3 × 2
-
Associative Property: The order in which numbers are multiplied does not change the product
- Example: (2 × 3) × 4 = 2 × (3 × 4)
-
Distributive Property: Multiplication can be distributed over addition
- Example: 2 × (3 + 4) = 2 × 3 + 2 × 4

- Matrix Multiplication: Multiplication of matrices (arrays of numbers)
- Vector Multiplication: Multiplication of vectors (quantities with magnitude and direction)
Multiplication Rules
- Multiplication by 0: Any number multiplied by 0 is 0
- Multiplication by 1: Any number multiplied by 1 is itself
- Multiplication by -1: Any number multiplied by -1 is its negative
Multiplication Tables
- A multiplication table is a table that shows the products of multiplying numbers from 0 to 9 by each other
- Used to help memorize multiplication facts and improve calculation speed
