Not so simple math: For me…anyway! 230-220x0.5=? You probably won’t believe this, but the answer is 5! This was sent to me by my Son (much smarter than I). Silly me, I answered 5...

For me…anyway!

230-220x0.5=?

You probably won’t believe this, but the answer is 5!

This was sent to me by my Son (much smarter than I).

Silly me, I answered 5 immediately and was made aware I am wrong…

Apparently, some Nerd with way too much time on their hands has come up a different way to do math.
I am sure that many of you (who are also smarter than I) already know this?

According to the kid, the Sequence (Order?) of Operations determined the answer is 5! Apparently, multiplication trumps subtraction, therefore is performed first in the equation…so forget the original 230. 220x0.5=110. Now subtract 110 from the 230 and you get 120. 120 apparently is equivalent to 5!
5! Is derived by multiplying 5x4x3x2x1
When I graduated, Pluto was still a planet and there was no punctuation in math (as I recall, anyway).
Who thinks up this stuff? And where will it ever be useful?
I hope to someday have to owe my Son $120 and I will write him a check for 5! 😂
I sure hope my Grandkids don’t ask me for help with their homework 🤦🏼‍♂️
Have a great day, all!

I got 5 when I saw it but ask your son because I’m not that smart but shouldn’t it be written (230-220)x0.5=?

Yup, follow the rules it’s 120..but I’m old too, so if I have 230 of something and gonna get rid of 220 of them and want to know what half of what’ll be left over it 5 d#**** but it has to be written (230-220)x 0.5=5

No one special

First, any operation in parentheses is performed, then multiplication and division, then addition and subtraction.
(230 - 220) x 0.5 = 5. 230 - 220 x0.5 = 230 - 220/2 = 230 - 110 = 120 = 5!. 5! is called 5 factorial. Any number factorial is that # x (#-1) x (#-2) etc. down to # x 1. Open the calculator on your computer and choose the scientific calculator. You should see a button named "n!". This will calculate the factorial of any integer. For example, 4! = 24, 6! = 720.

Sounds like something the Banks and Infernal Revenue Service (IRS) came up with.

Is one and one still two?😨

Your formula would be 5, but with out the parenthesis you multiply first.

The Meme he sent did not include the parentheses, but my dumbass still came up with 5 🤦🏼‍♂️ (I don’t remember being taught this, but it was a few years ago…like 45)
Glad someone understands this, though.

I got it now I think.🤞🏻 Funny thing is I use numbers everyday, even use some geometry and algebra. Can do it in my head.

Yep, was the way I learned it in 1950-60s, 120. if there had been parentheses that had included 230-220 like (230-220) then the ans would have been 5.
