In mathematics, summation is the addition of a sequence of numbers, called addends or summands; the result is their sum or total. Beside numbers, other types of values can be summed as well: functions, vectors, matrices, polynomials and, in general, elements of any type of mathematical objects on which an operation denoted "+" is defined.
A sum is the result you get when you add a sequence of numbers together. While summation typically involves numbers, the same addition process can be applied to many other mathematical objects like functions, vectors, and matrices, making it a fundamental operation across different areas of mathematics.
