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

I thought the answer was 78.





42.

If you solve it lefttoright, 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







Actually, your teacher realized you are more intelligent than him and he was embarrassed about that so he tried to cover for it by saying you were wrong.
I wouldn't try to stick it to him or prove your correctness I would just let it go. There is really no point in upsetting the guy who gives you your final grade.





ooh, come to think of it your teacher might be referring to order of precedence for calculating algebra expressions. You might get the "correct" answer from him if you enforce your concept by expressing it something like (230  220) x 0.5, for this the answer is 5. Your teacher may have been implying that multiplication is calculated before subtraction, so he might be reading it as 230  (220 x 0.5). It might be worth it to ask him if this is what he was thinking.
