What is the meaning of the symbol \(\Sigma ?\) Give an example with your description.

Short Answer

Expert verified
The symbol \(\Sigma\) stands for summation in mathematics, it represents the addition of a sequence of numbers. An example would be \(\Sigma_{i=1}^{4} i = 1 + 2 + 3 + 4 = 10\).

Step by step solution

01

Define the symbol

The symbol \(\Sigma\) is the uppercase Greek letter Sigma. In mathematics, \(\Sigma\) is commonly used to denote a summation, meaning the addition of a sequence of numbers.
02

Provide an example

An example of this could be the sum of the first four terms of a series: \(\Sigma_{i=1}^{4} i\), which stands for the summation of values from \(i = 1\) to \(i = 4\). In this case, that would be: 1 + 2 + 3 + 4 = 10.
