Go through each letter one by one, I will bold each step in order.
8-1*0+2/2 8-0+2/2 8-0+1 8+1 9
Basically, you didnt have Parenthesis, so next you look for Exponents, you didnt have any so next Multiplication or division, you had both so you do whichever comes first from left to right, in this case, 1*0, so you solve and keep going, you still have that division left, 2/2, so you do that. Afterwards you go through the steps from where you left off, Addition or Subtraction, you have both, again, do whichever comes first, in this case 8-0, then again 8+1. FInally you solve to get your answer.
