This is the summation symbol in mathematics, it represents the sum of a sequence of numbers.
This is the summation symbol in mathematics, it represents the sum of a sequence of numbers. It simplifies the notation for adding a series of terms, typically expressed as \(\sum_{\htmlClass{sdt-0000000018}{i} = \htmlClass{sdt-0000000121}{a}}^{\htmlClass{sdt-0000000033}{b}} \htmlClass{sdt-0000000003}{x}_{\htmlClass{sdt-0000000018}{i}}\) which means the sum of all \(\htmlClass{sdt-0000000003}{x}_{\htmlClass{sdt-0000000018}{i}}\) terms for \(\htmlClass{sdt-0000000018}{i}\) ranging from \(\htmlClass{sdt-0000000121}{a}\) to \(\htmlClass{sdt-0000000033}{b}\). This notation is widely used in various fields of mathematics, including statistics, calculus, and algebra.
