25 - ⁵/₅ = 25 - 1 = 24
If you wrote it vertically:
25 - 5
————— = 4
5
But once you lay it out on one line, you have to use prins to prioritize addition / subtraction:
(25 - 5) / 5 = 20 / 5 = 4
Some YouTube mathematicians deep-dive into this.
ETA: Nothing goes over my head! My reflexes are too fast, I would catch it.
The joke is 4! (Factorial) Is 24 so it looks right even if you do order of operations incorrectly.
Ok so I'm not dumb! Usually I am with math but I got this one. Go me!
Yeah and 24 = 4 factorial = 4!
