I started playing Wordscapes a few weeks ago. Combinatorics followed me because this is how I think about it:

If I have 6 unique letters, there are 6! = 720 ways to arrange those 6 letters. If I have 6 letters with some repetition, such as in the word "banana" then there are 6!/3!*2!*1! = 120 ways to arrange those letters. That's because there is no difference between "a" and "a" and "a", so we clip them by dividing 3! out of 6!, etc. for all repeated letters.

I was also pretty stunned to see that the word "Echelon" was one of the words on the board. I've only ever heard that in the context of a math class (Row Echelon form from Linear Algebra), so it's weird to me they would expect someone to figure that out. Most of the words were pretty common.

Anyway, I'm a nerd. 😂🤓
