This ‘maths meme’ has people scratching their heads. Can you solve it?

All those years of BODMAS and x= this and y=that may have made you wonder, “But where will I ever use this?” Well, who knew years after school, those same equations would come back to haunt you in the form of viral online puzzles. Take for this example this “maths meme” that’s created a stir on not one but at least two social media platforms. This “funny rather than stupid” equation has many scratching their heads for the correct explanation and some going “aah” over the answer. So which of these two sides features you?
Twitter user @kj_cheetham posted this little puzzle of sorts on the micro blogging site on July 13. Not only did it collect explanations and answers from tweeple, it also made its way to Facebook where more people tired it.

A maths meme that is actually funny rather than stupid:— KJ Cheetham ❄️ #FBPE 🔶 (@kj_cheetham) July 13, 2019
230 - 220 x 0.5 =
You probably won’t believe it but the answer is 5!#maths
While on Twitter the puzzle has collected over 57,000 ‘likes’ and more than 24,000 retweets, on Facebook, a snapshot of the tweet has collected over 980 shares and more than 5,000 reactions since it was posted on July 14.
So have you managed to arrive at the right answer? If you’re confused, don’t worry. Several others have felt the same way. Here’s how some have solved this:
Ambiguously worded question:— Richard Bentall #FBPE (@RichardBentall) July 13, 2019
(230-220) x 0.5 = 5
230 - (220 x 0.5) = 120
No, it’s 120, unless it’s written (230-220) x 0.5.— David Hazel #FBPE #PeoplesVote 🇬🇧🇪🇺 (@dhazel418) July 13, 2019
Multiplication has a higher priority than addition or subtraction, unless overridden by brackets
All I have to say to you is BODMAS!— Richard Beasley #FBPE #RevokeA50 (@richbsys) July 13, 2019
You need brackets for the answer to be 5
230-220*0,5=— ((( Kevin Karhan ))) 🛡️ #PNCHNZS 24/7! (@k3vk4) July 14, 2019
How does this equate 5?
Here’s the solution:
For those who are missing how this could be true with traditional order of operations, note that 5 is not 5!— James Schloss (@LeiosOS) July 14, 2019
Here "!" is not an exclamation point, but a factorial.
I thought it was clever and want to make sure everyone else does too.
That's right.— RichifyMeClub (@RichifyMeClub) July 15, 2019
Factorial of 5 = 5x4x3x2x1
And here’s how people have reacted to the solution:

YOU BASTARD!!!— Nullfidic 🇨🇦 Newfie (@BobbieDeep) July 14, 2019
Thanks. I needed that laugh.
V funny but wrong - or at least ungrammatical. If the ! represents factorial, then there should be a full stop ( or other sentence end symbol) after it. There isn't, so the ! must be the sentence end symbol, not a factorial symbol - or there is a punctuation fail. :)— Pete Watts (@BluffKingHal) July 13, 2019
Umm, but its obvious its 5 .... Not sure why I wouldnt believe it as I was taught this in school. Weird that this is such a popular tweet or requires retweeting.— Daveo (@inflammatorydev) July 15, 2019
Is it 5? No! It is 5!— Stefan Rahmstorf (@rahmstorf) July 14, 2019
So what do you think of the “maths meme”?
