Answer:
The answer is 12
Step-by-step explanation:
First, you do 2+8=10. You do that first becuase it is in the parentheses
After that, You do 15+3=18
Then, 4 and the 2 over it. Which is a exponent. And that tells you to multiple the number by itself. So 4x4=16.
But it also says subtract the 4. So now you Add the 10+18=28
Then you subtract 16 from 28. 28-16=12.
Thats how you get your answer.
