#### Explanation:

Order of operations: parentheses/brackets, exponents, multiplication/division, and addition/subtraction

Since there are no parentheses, the exponent has to be evaluated first:

$25 - 8 \cdot 2 + {3}^{2}$

$25 - 8 \cdot 2 + 9 \rightarrow$ Next comes multiplication

$25 - 16 + 9 \rightarrow$ Now there's just subtraction and then addition (follow the order in which it is written)

$9 + 9$
