Also called sigma notation, summation notation allows us to sum a series of expressions quickly and easily, especially when using a calculator. The free tool below will allow you to calculate the summation of an expression. In LaTeX, the operator is \sum Ask a new question Source codeĭCode retains ownership of the "Summation Σ" source code. First of all, it is easy enough to add these numbers either in your head or with a calculator. Summation notation (or sigma notation) allows us to write a long sum in a single expression. This is a challenging, yet important step towards a formal definition of the definite integral. ![]() ![]() In Greek, sigma corresponds to the letter S (like the first letter of Sum). Suppose you encounter the following problem, 1+3+5+7+9+11+13. Summation notation can be used to write Riemann sums in a compact way. The summation is written with the dedicated mathematical operator ∑ ( Unicode U+2211) inspired from the Greek letter sigma uppercase Σ ( Unicode U+03A3). ![]()
