Question

Can someone help me please?

Answer 1

We are using PEMDAS or Oder of Operations for this. So for this problem we have to use the brackets which are in place of the parentheses.

15-8=7

Then we go back and do 10×8 which is 80

Then add 80+7 to get 87

Answer is A

Answer 2

10 x 8 +(15-8)
80+15-8
87....A. is the answer
