- Sum[List]
- Calculates the sum of all list elements.
- Note: This command works for numbers, points, vectors, text, and functions.

Examples:

`Sum[{1, 2, 3}]`gives you a number*a = 6*.`Sum[{x^2, x^3}]`gives you*f(x) = x*.^{2}+ x^{3}`Sum[Sequence[i,i,1,100]]`gives you a number*a = 5050*.`Sum[{(1, 2), (2, 3)}]`gives you a point*A = (3, 5)*.`Sum[{(1, 2), 3}]`gives you point*B = (4, 2)*.`Sum[{"a","b","c"}]`gives you the text*"abc"*.

- Sum[List, Number n of Elements]
- Calculates the sum of the first
*n*list elements. - Note: This command works for numbers, points, vectors, text, and functions.
- Example:
`Sum[{1, 2, 3, 4, 5, 6}, 4]`gives you the number*a = 10*.
