# How do you evaluate [7-(3-6(5-3)+2)]+7?

Mar 3, 2018

in his type of question we first have to solve the inner brackets
the answer is $21$

#### Explanation:

so first we will solve the inner brackets
$\left[7 - \left(3 - 6 \left(5 - 3\right) + 2\right)\right] + 7$

the 5-3 is in the inner brackets so $5 - 3 = 2$

$\left[7 - \left(3 - 6 \left(2\right) + 2\right)\right] + 7$
multiplying $6$ by $2$ which equals $12$

$\left[7 - \left(3 - 12 + 2\right)\right] + 7$
calculating numbers in the bracket

$\left[7 - \left(- 7\right)\right] + 7$
if we have a negative outside a bracket, it will change the signs of all the numbers in the bracket. if it is $-$ it will become + and if it is + it will become -

so $7 + 7 + 7$ $= 21$
