Question

What is the value of `8^2 - (3+2*2) *6` using PEMDAS?

Answer 1

`22`

Explanation:

There are two terms.Workout an answer for each and add them in the LAST step.
Within each term do powers and roots first, then multiply and divide. If there are parentheses these over-ride the usual order so that weaker operations must be done before the stronger ones.

`color(magenta)(8^2)color(blue)( - (3+color(red)(2xx2)) xx6)`

=`color(magenta)(64)color(blue)( - (3+color(red)(4)) xx6)`

=`color(magenta)(64)color(blue)( - color(red)((7)) xx6)`

=`color(magenta)(64)color(blue)( - color(red)((42)`

=`64-42`

=`22`
