How do you simplify 8 + 5[ 10 + 10 ÷ 2] using order of operations?

83

Explanation:

Due to the PEMDAS rule, brackets will have to go first.
$8 + 5 \left[\textcolor{red}{10 + 10 \div 2}\right]$
If a number has already been given after solving a problem that was in brackets, a multiplication sign should be there before the answer. So it will be this:
$8 + 5 \times \textcolor{red}{15}$
There aren't any exponents, but there is multiplication, so it'll go next.
$8 + \textcolor{red}{5 \times 15}$
So it will be this:
$8 + \textcolor{red}{75}$
Finally, we will have to do addition.
$\textcolor{red}{8 + 75}$
So the final answer is 83. Hope this helped!
