Hello, jenni_ann_t!

Start in the "inside" and simplify one step at a time:

$\displaystyle \;\;\;\;\bigg(\left[(\underbrace{10\,+\,8})\,\times\,2\right]\,-\,3\bigg)\,\div\,3$
. . . . . . . . . $\displaystyle \downarrow$
$\displaystyle \;\;\;=\;\bigg(\left[\underbrace{18\,\times\,2}\right]\,-\,3\bigg)\,\div\,3$
. . . . . . . . . .$\displaystyle \downarrow$
$\displaystyle \;\;\;\;\;=\;\left(\underbrace{36\,-\,3}\right)\,\div\,3$
. . . . . . . . . . . $\displaystyle \downarrow$
$\displaystyle \;\;\;\;\:\ \ \ =\;\underbrace{33\,\div\,3}$
. . . . . . . . . . . . . $\displaystyle \downarrow$
$\displaystyle \;\;\;\;\;\;\;\,\;\;=\; 11$

Thank you.

Edit: Never mind. You already have a fully-worked solution.
