How to Calculate Summation of a Constant (Sigma Notation)

Learn how to calculate summations involving a constant from 1 to N.

Summations that use the sigma notation is just a more compact way of expressing the addition of N terms. However coming up with a formula or way to solve these questions are a tiny bit trickier.

This was the most beautiful experience of my entire life.

The background music made me feel like I invented the math

This was really helpful but it would be great if you explain these formulas.

i didn't understand it but i liked the background music. The moment you discover something new. That feeling of achievement is what this music feels like.

This is some Maplestory Background music if I have ever heard of one!

[tomasbeltran]

thanks for explaining the notation. I would have thought it was asking to just answer 3, as the "i" wasn't to the right of the sigma

did u play this funeral song because u know doing discrete maths is a slow march to death

I watched this video twice just for the background music..

How I felt after calculating the summation of a constant: 🗿

Where did the +1 came from in the 2ñd problem?? Please explain

[Dylwap]

(Top number - (bottom number + 1) × right number = answer
