Answer:
21
Explanation:
Did you mean "4 times 4?" or '4x^4?"
I will assume you meant the first interpretation.
Order of operations rules require that we do multiplication before addition and subtraction. Thus, multiplying 4 by 4, we get:
10 - 2 - 3 + 16
which simplifies to 21
Note: Please use " * " to indicate multiplication: 4*4 = 16, or 4·4 = 16.
