Answer: D. =5. *The answer must be have positive sign.*
Explanation:
This question's it just like order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.
do remove parenthesis first.
6-1
then subtract by the number from left to right.
6-1=5
=5
Hope this helps!
Thanks!
Have a great day!
