Multiplication and Division Basics

Building Blocks for Multiplication and Division

Multiplication is a quick way to add the same number many times. Division is breaking a number into equal groups.

Multiplication

If you have 3 bags with 4 apples each, you can add 4 + 4 + 4 or multiply \(3 \times 4 = 12\).

Division

Suppose you have 12 cookies and want to share them with 3 friends. You divide: \(12 \div 3 = 4\). Each friend gets 4 cookies.

Tips

  • Use arrays or groups of objects to visualize.
  • Practice times tables to get faster.

Key Formula

\[a \times b = c\]

Examples

  • 5 × 3 = 15

  • 20 ÷ 4 = 5

In a Nutshell

Multiplication adds groups; division splits into groups.
