Sum
A sum is the result of an addition. For example, adding 1, 2, 3, and 4 gives the sum 10, written 1 + 2 + 3 + 4 = 10. The numbers being summed are called addends, or sometimes summands. The summation operation can also be indicated using a capital sigma with upper and lower limits written above and below, and the index indicated below. For example, the above sum could be written sum_(k = 1)^4 k = 10. The sum of a list of numbers is implemented as Total[list].
