Calculate numbers with a mixture of brackets, addition, subtraction, multiplication, division and exponents in the **wrong** order, and you will get a **wrong** answer !

**wrong**order, and you will get a

**wrong**answer !

6 x (5 +3) = 6 x 8 = 48

or is this the answer?

6 x (5 +3) = 30 + 3 = 33

So, long ago people agreed to always follow certain rules when doing calculations, and they are:

It makes a difference to the calculation which parts you solve first.

6 × (5 + 3) | = | 6 × 8 | = | 48 |
|||

6 × (5 + 3) | = | 30 + 3 | = | 33 | (wrong) |

First the items in the brackets are calculated, then divide and multiplication, then addition and subtraction.
