A viral math equation is trending and confusing netizens, it all started with KJ Cheetham sharing a simple equation 230 – 220 x 0.5 =? He gave the answer as 5! but people on twitter was not convinced. Here is the official tweet from him
A maths meme that is actually funny rather than stupid:
Solve carefully!
230 – 220 x 0.5 =You probably won’t believe it but the answer is 5!#maths

Most aren’t buying that as they are of the opinion that 120 is the correct answer to the problem 230 – 220 x 0.5 =?
If you solve it by subtraction 220 from 230 and multiply it by 0.5 the answer is pretty obvious as 5.
It was a huge debate with the original poster muting his tweet and posted the following
Dear all, I'm going to mute my own notifications on this thread shortly, but please remember to think twice before claiming someone doesn't know something, based on a single tweet! ?

Some spoke about BODMAS and said the multiplication should be performed first and then subtraction. Then on looking closer it was concluded that he meant 5! (5 factorial) which is 5*4*3*2*1= 120
So he is right, the answer is 120 aka 5! (5 Factorial) 😉
Equation is 230-220×5
=5(230-220)
= 115-110
= 5
So,the answer is 5
its wrong,
230-220×0.5
apply BODMAS
220X0.5=110
230-110=120=5!….n its written 5! in answer also
not 5
The author of this task is wrong, he uses punctuation everywhere, except in the end. So he answered wrong on his own task, since his answer is “5” and then exclamation mark, which ends the sentence.
If he wants to say factorial of 5, then it should be “5!.” or “5!!” with exclamation mark indicating the factorial and then either the period or exclamation, which ends the sentence.
So in the end he’s wrong, because the answer isn’t 5, it’s 120 or 5!.
Actually, 5!! is still ambiguous, because there is a double factorial function. In fact, 5!! = 15.
its 120
