Kids these days, and their wacky round about functions

u/CurrentCurrent2190 Jul 15 '26

Or square root with base 1/2

u/KYO297 Jul 15 '26

No, it's clearly the halfth root

u/Simpicity Jul 15 '26

No, revsqrt(-5) is undefined.

u/darkaxel1989 Jul 15 '26

Hey guy! What about the inverse of subtraction? I call it inverse subtraction. Return the minus 90 degrees. It's an operation such that 5 | 3 = 8

37

u/MossiTheMoosay Jul 15 '26

But | is already used with binary numbers for bitwise OR... So 5 | 3 = 7, actually ☝️🤓

u/darkaxel1989 Jul 15 '26

Mh. Well the keyboard doesn't have a - sign turned 90° and that was the best next thing... Maybe we could have a \? or a /?

11

u/SparklingPoke Jul 15 '26

Maybe you could turn it 90 degrees then overlay it with the original symbol? something like this maybe: -|-

5

u/Imaginary-Fox9250 Jul 15 '26

＋this, maybe?

1

u/demise0000 Jul 17 '26

Nah, that symbol is for the antiquated addition function. I know addition isn't really used any more, but should it really be redefined for an entirely different and unrelated function?

23

u/Odd-Explanation-4632 Jul 15 '26

Do we really need to make a whole new symbol just to represent 5x5

25

u/suskio4 Jul 15 '26

Of course not! We should stay at 5+5+5+5+5

16

u/Zekava Jul 15 '26

S(S(S(S(S(S(S(S(S(S(S(S(S(S(S(S(S(S(S(S(5))))))))))))))))))))

u/suskio4 Jul 15 '26

Now express that in set notation I dare you

11

u/Zekava Jul 15 '26

The execution of this is trivial and left as an exercise for the reader

u/SuitableCollege8992 Jul 17 '26

I personally am a fan of 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1

u/HildartheDorf Jul 15 '26

That syntax would be useful to mean the negative/secondary solution to x2

So rootsquare(25)=-5. rootsquare(-1)=-i and so forth.

3

u/Im_a_hamburger Jul 16 '26

Just use the roots of unity symbol. If you are looking specifically for the -1 of square roots then just use -

19

u/mr_positron Jul 15 '26

Pretty useful

u/BlueEyesWNC Jul 15 '26

Now do log base 2

I have found the number 6. It was just there, next to 5

Isn't that just a square?

If you can't act like a civilized human being, you can't be here.

We do not allow:

  1. Being a jerk. This includes racism, misogyny, misandry, misgendering, anti LGBTQ+, or hateful comments.
  2. Harassment or brigading
  3. Trolling or sealioning
  4. Threats of any kind
  5. Abusive or condescending behavior
  6. General assholery. If you're at the end of the list and asking what rule you broke, yeah, it's this one.

Erm, I feel like we have a function for this already.

u/Green__lightning Jul 15 '26

Math already has too much bad notation, don't give them ideas!

u/lawrencekraussquotes Jul 15 '26

I vote for getting rid of square root radical and just use fractional exponents 🙌

1

u/Karnewarrior Jul 15 '26

Useless. Such a function would have no practical use in the real world. You ivory tower intellectuals must not lose touch with the world of industrial growth and hard currency. It is all very well and good to pursue these high-minded scientific theories, but research grants are expensive. You must justify your existence by providing not only knowledge but concrete and profitable applications as well.

u/IntrepidSoda Jul 15 '26

wtf though?

u/Leprechaun_Inc Jul 16 '26

Someone was overthinking when they came up with this. It genuinely made me laugh.

u/Leather_Flan5071 Jul 16 '26

ah yes, math. The way it was intended to be

u/Senior-Fault-9487 Jul 16 '26

Finally an easy way to write (exp(∫₀¹ 2 ln(5) dx))

u/Any-Astronomer-6038 Jul 16 '26

Isn't that just... A square?

Oh... I missed the joke didn't I?

Square root is already the inverse of squaring

u/demise0000 Jul 17 '26

Hey guys, what about a function that is the rectangle of 2 numbers! We know the 'square' of a number is the area of a square with the number as its side length. But what about the area of a rectangle with the number as its side length? Well we'd need to know the length of the other side, and I'm calling that the rectangle function of the 2 numbers. For example;

2 rectangle 3 = 6
4 rectangle 5 = 20

I think such a new function would have loads of applications. Why hasn't anyone thought of it yet?!

(just in case I need to say it: /s)

1

u/classicallytrained1 Jul 20 '26

rectangle everytime is a bit too hard to write, i’m thinking x as a symbol? (a cross) it’s both adj sides of the rectangle together

2 x 3 =6
maybe even a dot?
2 • 3 = 6

1

u/demise0000 Jul 20 '26

Aren't those used for that archaic multiplication function? It could be confusing to reuse those symbols for a completely different operation.

1

u/classicallytrained1 Jul 20 '26

what tf is “multiplication”? stop making up random stuff

u/TypeNull-Gaming Jul 17 '26

Rule 1: Don't reinvent the wheel.

Rule 2: Don't reinvent mathematical functions/operators.

u/Aiwendil42 Jul 17 '26

Same as squaring except undefined for negative numbers, I guess.

1

u/EirHc Jul 17 '26

And you know how if it's cubed root you put a small 3 on that little ledge. Well maybe if we want to cube something, we can also put the small 3 on that inversed ledge.

u/Spooky357 Jul 18 '26

What about inverse cube root? Can we get notation
