Year 8: Order of Operations

The order of operations is a set of rules to follow when solving mathematical calculations. It ensures everyone gets the same answer!

The Acronym: BODMAS

Remember this acronym to help you:

• Brackets
• Oorder (Indices or Powers)
• Multiplication and Division
• Addition and Subtraction

Explanation

1. Brackets: Solve anything inside brackets first. These are the most important!
2. Indices/Powers: Calculate any powers (e.g., 2³ = 8).
3. Multiplication and Division: Work these from left to right, just like reading a sentence.
4. Addition and Subtraction: Finally, work these out from left to right.

Example

2 + 3 x 4

1. Parentheses: None.

2. Multiplication: 3 x 4 = 12

3. Addition: 2 + 12 = 14

Answer: 14
