You are wrong, the teacher is right.

The order of precedence in mathematical operations is (mnemonic PEMDAS):

Parentheses
Exponentiation
Multiplication & Division
Addition & Subtraction

If two operations have the same precedence, they are evaluated from left to right. Your problem may be rewritten as 230 - (220 x 0.5), the answer to which is obviously not 5.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.
