# What is 25- ( 2+ ( 4- 2)^{2} ) + 10?

Sep 11, 2016

$29$

#### Explanation:

Always count the number of terms first. EAch term will give a final answer and these are added or subtracted (left to right) in the final step.

The expression has 3 terms, but there are 2 separate terms inside the bracket.

$25 - \left(2 + {\textcolor{red}{\left(4 - 2\right)}}^{2}\right) + 10$

=$25 - \left(2 + \textcolor{b l u e}{{\left(2\right)}^{2}}\right) + 10$

=$25 - \textcolor{\lim e}{\left(2 + 4\right)} + 10$

=$\textcolor{m a \ge n t a}{25} - 6 \textcolor{m a \ge n t a}{+ 10} \text{ } \leftarrow$ 3 terms: calculate from left to right

OR

=$\textcolor{m a \ge n t a}{25 + 10} - 6 \text{ } \leftarrow$ re-arrange with + at the front

=$29$
