The answer is 1600. 40 times 40.
This is easy. You do order of operations which is P, E, M, D, A, S. Therefore 5 x 2 is 10. 50-10 is 40. 40 x 40 is 1600. The answer is 3. 1600. I thought if I gave a more detailed answer and the fact that im one of your contacts would give me best answer, lol.

P=parentheses
E=exponents
M=multiplication
D=division
A=addition
S=subtraction
