#### Explanation:

You must use the order of operation .
If you get hurt in PE call a MD As Soon as possible
( compliments of the students from Carr middle school Santa Ana CA.)

P = parathesis
E = exponents.
MD = Multiplication and Division ( an MD doctor is one person so multiplication and division must be done at the same time from left to right
AS = Addition and Subtraction ( As soon as possible is one time so addition and subtraction must be done at the same time from left to right.
Start with the inter most parenthesis and work outward.

${\left(9 - 8\right)}^{2} = {\left(1\right)}^{2} = 1$
${\left(12 - 5\right)}^{2} = {\left(7\right)}^{2} = 49$

putting this values into the expression gives

$2 \left(1 + 49\right) = 2 \left(50\right) = 100$

The answer is 100
