# How do you find the sum of Sigma i^2 where i is [0,4]?

Mar 14, 2018

The sum is equal to $30$.

#### Explanation:

This sigma notation is asking to sum up all square numbers from $0$ to $4$.

I'll write out the whole notation:

$\textcolor{w h i t e}{=} {\sum}_{i = 0}^{4} {i}^{2}$

$= {0}^{2} + {1}^{2} + {2}^{2} + {3}^{2} + {4}^{2}$

$= 0 + 1 + 4 + 9 + 16$

$= 1 + 4 + 9 + 16$

$= 5 + 9 + 16$

$= 14 + 16$

$= 30$

That's the result. I hope this helped!
