Hi Learning Math;

Welcome to the forum!


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Re: Just saying hello

Hi Hotel8561

A triangular pyramid has 3 vertices on the base and one more at the top = 4 altogether.

A triangular prism has 3 vertices to make one end, another 3 at the other end so 6 altogether.

Look at:
