Capital PI notation helps. Exponentiation is repeated multiplication & empty product = 1. If a≠0 & n∈ℕpic.twitter.com/qK6VAP7ACK

Weird notation.
My brain just exploded!!!!
very nice
That also shows the problem with 0^0
Same as n^0 = n^(x-x) =(n^x).(n^-x) =(n^x)/(n^x)=1
That’s pretty cool.
I love this.
