Can you explain what summation notation is?
Sure! Summation notation is a way to represent the sum of a sequence of numbers using the sigma symbol (Σ).
How does it work? Can you give me an example?
Of course! For example, Σ from i=1 to n of i means you add all integers from 1 to n.
What are some common uses of summation notation?
It's commonly used in mathematics, statistics, and computer science, especially for series and sequences.
Can you show me how to calculate a specific summation?
Absolutely! If you want to calculate Σ from i=1 to 5 of i, you would add 1 + 2 + 3 + 4 + 5, which equals 15.
