1,849 views

The general rule for summation involves adding a series of numbers together. Mathematically, it is often expressed using the sigma notation (∑). For example, the sum of numbers from 1 to n can be written as ∑(i=1 to n) of i, which equals n(n + 1)/2. This rule simplifies the process of adding consecutive numbers.
