He is not wrong. You just didn't see the entire answer in your brain. The exclamation point is there for a reason.

Have you write 5! as answer, or it is only for us as an expression of your frustration?

You teacher was right, and told you the correct result was actually 76 .
Could you please tell us why?

If you solve it left-to-right, ignoring precedence order, then the answer is 5. An old TI calculator would give you that answer. Today's windows calculator will not: it says 120 because the multiplication is done first.

"5!" = 120
It's a clever nerdy riddle. I like it!
I wonder if I'd have been hassled after math class for giving such an answer?
and I just noticed that Microsoft Excel doesn't recognize factorials.

The teacher was not embarrassed but shocked that any student could be so wrong. The division MUST be carried out before the subtraction. 230 – 220 × 0.5 = 230 – 110 = 120. Try it in any scientific calculator or programming language. You are alone (I hope) in thinking the answer is 5. Are you perhaps joking?

As with a few readers, you missed the ! after the 5.

this is excellent!

That pesky little exclamation mark...
|
|
|
|
|
Oh, come on! I immediately saw that: 5!=120
|
|
|
|

Is it because you are saying 5! (factorial). 230 - 220 x 0.5 = 230 - 110 = 120 which is == 5x4x3x2x1 or 5!.
|

Your answer is wrong, but not because of maths but because of your English usage. Your intention is to say the answer is 5 factorial in which case your first sentence would end with:
"and announced that the answer was 5!."
However, by leaving off the period, the exclamation mark ends the sentence, which means you are actually saying the answer is 5.
I realize leaving off the period was deliberate to make the trick work, but it's inaccurate, and we are all engineers here
