# How do you evaluate 51-2*13+14?

Aug 6, 2016

$39$

#### Explanation:

If there are several operations in an expression, count the number of terms first. Each term simplifies to a single answer. The answers are added or subtracted in the last step.

Powers and roots are done first because they are the strongest operations Then Multiply and divide and last add and subtract because they are the weakest operations.

If a weaker operation is to be done first it is put in brackets. So if brackets are there, they must be done first.

$51 - 2 \times 13 + 14 \text{ there are three terms}$

=$51 - 26 + 14$

=$39$

Note that by following PEDMAS /BODMAS, the addition in this case is
$51 + 14$ The subtraction is -26.

Do NOT make the mistake of doing 51-(26+14)#
