Question

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

Answer 1

83

Explanation:

Due to the PEMDAS rule, brackets will have to go first.
`8+5[color(red)(10+10div2)]`
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+5xxcolor(red)(15)`
There aren't any exponents, but there is multiplication, so it'll go next.
`8+color(red)(5xx15)`
So it will be this:
`8+color(red)(75)`
Finally, we will have to do addition.
`color(red)(8+75)`
So the final answer is 83. Hope this helped!
