The summation symbol is known as the "Sigma".

'; explain[1] = '#2

Sigma resembles a cross between an E and a Z. We think it looks closest to a E.

'; explain[2] = '#3

Sigma notation is the easiest way to represent a sum of a sequence.

'; explain[3] = '#4

Permutation and Combinations are the 2 types of combination type functions.

'; explain[4] = '#5

Permutation deals with the order that each combination is in also.
