Correct. Nothing to see here, move on.0

(230-220) x 0.5
10 halved (as 0.5 is half a whole number)
10 x 0.5 = 52 -
230 - (220 x 0.5) = 120
5! = 5x4x3x2x1 = 120

Am sure we have had multiple bidmas/Bodmas type questions on here before0 -
I think we’ve had this exact one before.5! not 5 is what makes it correct.4

to explain 5factorial (5!) in more detail
5! = 5 × 4 × 3 × 2 × 1 = 120

In fact, it was the exact same title.
Furthermore, it was the same person who created the thread.

My trusty old scientific calculator which has got me through 12/13 accounts exams to date says 120!0

120. I’m sure we had a thread like this before. That’s the only way I concluded it’s 120 rather than 5.0

Need to know what part of the equation to do first. If you take it at face value then the answer is 5. But put a couple of brackets in & it would change the answer completely.
Edit.
No idea what an exclamation mark at the end means - never used it when I was at school in the early 80's but then I only did "O" level maths. I just thought Chizz was exclaiming the answer.1 -

The question is not 'what is the factorial of this equation'0 -

The bloke who created the theory behind this died at 20 so shouldn't be too difficult.1 -

Edit - I am wrong. 5! = 120. Thank-you for introducing me to factorials. If I'd bothered to read the thread I'd have discovered this by post 4.
I've been sums shamed.3
