You can put this solution on YOUR website!
This only requires knowing order of operations. The confusion I find is in how you arranged your rendering tags.

I will assume you mean this:
3+-+%28-7%29%2A3%5E2++%2B+37+%2B+%28-7%29%5E2

Parentheses first.
Just as you have,
3+-+%28-7%29%2A3%5E2++%2B+37+%2B+%28-7%29%5E2

EXPONENTS.
3-%28-7%29%2A9%2B37%2B49

MULTIPLICATIONS AND DIVISIONS.
3-%28-63%29%2B37%2B49

And you can finish...?
