Question

What is `2(36-:4)+9-8`?

Answer 1

=`19`

Explanation:

It is most important to count the number of terms first. Each term will simplify to a single answer and these will be added or subtracted in the last step.
Within each term - brackets must be done first.
Then do the stronger operations of powers and roots.
Then do multiplication and division.

`2(color(red)(36div4)) color(blue)(+9)color(lime)(-8)` has 3 terms.

=`color(red)(2xx9) color(blue)(+9)color(lime)(-8)`

=`color(red)(18) color(blue)(+9)color(lime)(-8)`

=`19`
