I'm so impressed by the quality of that class. Well done!

[@PreMath]

Thank you so much!

Super easy. After seeing the thumbnail, I solved it on my own. Same drill as before, fast forwarded to the end to double check if my answer matches as the one in the video which turned out to be. Cheers from The Philippines 🇵🇭

[@LENAKSOY]

In general (x+2)! up on [( x+1)!+(x)!] = (x+1). x belongs to set of natural numbers.

[@honestadministrator]

This is of the form of factorial (n+1) / [ factorial (n) + factorial ( n -1) ] = (n +1) /[ 1 + 1/n] = n

Why isn't the simplified answer 2022! factorial included?

[@sureshmukhi2316]

Because it cancelled out. Only 2022 is the right answer.

[@MK06086]

answer is 2022?

The explanation and steps written in this problem and many others seems to be Childish and presumes a poor IQ level of target individuals at large.

2024! in the numerator divided by (2023! + 2022!), brings us up to speed. Projecting factorials is fun.🙂
