To solve this you will be needing to use PEMDAS! 
Parenthesis exponents multiply divide add subtract!
So first parenthesis...
609-78=531
So now we write the problem like this
10*80+531-10^2
Now exponents
10^2 is a exponent so that =10*10 which = 100
So we write it out again like this:  10*80+531-100
Now we need to multiply from left to write
So 10*80=800
Re-write it:
800+531-100
So now we need to add from left to write
800+531=1331
1331-100=1231
So your answer is 1231.
Does this help any?
