10*(80+5)6-1
wow im so confused because there is no + / * or - next to the 6 15 points

First Parenthesis
So we have 80+5=85.
Now let's rewrite the problem. 10*85*6-1. 
I put the * sign because when you have a number like this: (10+5)1 It means you will subtract it by the number outside of the parenthesis. Now we need to move onto multiplication because there are no exponents so we skip that. 
Lets multiply from left to right.
So we have 10*85*6-1 so lets start with 10*85=850
Now we have
850*6-1 So let's do 850*6=5100
Now 5100-1=5099
So your answer is 5099
