okhxyyo seems to like to post brain teasers. Now I will post one for okhxyyo: 0 0 0 0 = 24. There are four zeros on the left side of the equal sign and the number 24 on the right. Add an operation symbol (no numbers allowed) on the left side to make the left side equal to the right side. There are multiple solutions to this problem. See how many solutions okhxyyo can come up with.

Teacher, I was shocked~~ I'm so nervous. The teacher gave me a test~~ First answer 00:00=24 and then go to work. After finishing the work, I will think of other solutions. .

: Is it an operation symbol?

Come on, (0!+0!+0!+0!)!

1) (0! +0! +0! +0! )! = 24 2) [cos0+cos0+cos0+cos0]! = 24 3) [exp(0)+exp(0)+exp(0)+exp(0)]! 4) [(0!+0!)*(0!+0!)]!=(2*2)!=4!=24 4) [sin0+sin0+sin0+sin0]!=24 5) [tan0+tan0+tan0+tan0]!=24 6) [sinh(0)+sinh(0)+sinh(0)+sinh(0)]!=24 Hyperbolic sine 7) [cosh(0)+cosh(0)+cosh(0)+cosh(0)]!=24 Hyperbolic cosine 8) (sec0+sec0+sec0+sec0)! =24 Baidu, I don't know if it's correct

Um, when I first saw it, I thought of 24 o'clock, hahahaha~~~Another answer that came to my mind (0! +0! +0! +0!)! =24

There is also (exp0+exp0+exp0+exp0)! =24. lg1=0, reversed

Two 4). The second 4) is not correct. sin0=0. 5) is also not correct. tan0=0. 6) and 7) are obviously not both correct at the same time, just as 2) and the second 4) are not both correct at the same time.

Let's do one too (((0!+!0+0!)!)!!)>>(!0)

Another one ((0!)<<(0!)<<(0!))! + 0

This is so dizzying. . .

That is not a mathematical operation symbol.

There are no mathematical operators, cos, sin, etc. are functions.

cos, sin... should also be considered operators. Just like! is considered an operator.

I can only think of operations like addition, subtraction, multiplication, division and square root, but I can figure out trigonometric functions and factorials. I admire you.
