BEDMAS
BEDMAS means that the order that calculations are carried out is:
|
Brackets: |
Work out the value of any expressions inside brackets. |
|
Exponents: |
Work out the value of any numbers or expressions with exponents or indices. Sometimes shown as 'of ' meaning multiply. |
|
Division: Multiplication: |
If these two operations occur together, work from left to right. |
|
Addition: Subtraction: |
If these two operations occur together, work from left to right. |

|
3 + 4 × 5 |
Do Multiplying first |
3 + 4 × 5 = 3 + 20 = 23 |
|
4 + (6 − 2) |
Do Brackets first |
4 + (6 − 2) = 4 + 4 = 8 |
|
13 − 12 ÷ 6 + 4 |
Do Dividing first |
13 − 12 ÷ 6 + 4 = 13 − 2 + 4 =15 |
|
3 × 6 2 |
Do Exponent first |
3 × 6 2 = 3 × 36 = 108 |
| 14 − 5 + 6 | Work from left to right | 14 − 5 + 6 = 15 |
Most calculators
know all about BEDMAS but care should be taken when using a calculator to do calculations of this type.
