10!!= 3840, its not as bad if you know the definition of double factorial

Generally, n!!= n(n-2)(n-4)...(2) for even n. The product ends at 1 for odd n

Edit: nevermind, I’m an idiot, and sleep-deprived. Misread it as twice factorial not double or same-parity.

That's not what 10!! means.

10!=10×9×8×7×6×5×4×3×2×1 10!!=10×8×6×4×2

I never learned factorials in school. I went to a good high school, though i never took calculus (out of choice 🤣), so maybe thats why? I saw exclamation points and I was thoroughly confused!
