You won't believe it but the answer is 5!
230 - 220 x 0.5

I don't care.
This'll be one of those BODMAS or PEBMUD or RAGMER things which 'everyone' claims was taught at school but it clearly wasn't. If it doesn't have brackets, I have literally no way to interpret what comes first.

BODMAS - Brackets Off, then Division, them Multiplication, then Addition, and finally Subtraction.
If there are no brackets, then presumably you just follow the rest of the recipe from the D onwards... so the answer is 120 or 5, depending on perspective and real world use-case.
Dunno what the other two are, as I spent most of my maths lessons playing cards with the guy behind.

Love factorials. My favourite is 52! - the number of ways a deck of cards can be ordered.

So when you decently shuffle a deck of cards, there’s almost no chance that order has existed before.

haha
It's a play on 5! being 120 to try and catch people out saying "no it isn't" and then arguing about punctuation for ages and whether it should have been written as 5!. rather than 5! to actually mean it was a factorial and not the end of a sentence...

First you times, then you divide, then you take away. BODMAS, then you start all over again, hey!
O does not stand for Off.... it's for Orders
"Everyone" in the UK was taught it at School from 1988 onwards when it became part of the National Curriculum

What is the order of operations? - BBC Bitesize
The order of operations is the rule that tells you which bit of a calculation to do first. Find out more in this Bitesize Primary KS2 Maths guide.

KS2, apparently.
That'll be why! I was long gone by then.

Yeah, of course. It's basic maths
I was taught it in school, college and then uni, and doing SW Dev means I've never escaped it..
Wow, the days of my Uni lecturer going on about VPAM calculcators (Visually perfect algebraic method) and advising us they were the future!

My Irish maths teacher... imagine the punctuation... BODMUS... PAR... PAR...
"Sir.. What's PAR?"
"PAR... PAWR.... POOOOWAR... POOOOOWER.."
"Oh you mean POWER... 10 to the Power of 5..."
