On Quora, how do we type the summation symbol? πŸ₯‡



There are some ways to do that. First, you have to write β€œ\sum” and the sign will be displayed. If you want to add something after this sign you can do that by writing β€œ\sum_{i=0}^{n}” or β€œ\sum\limits_{i=0}^{n}”. Another way is to display sums separately from the text by typing β€œ\displaystyle\sum” so that the sum sign appears. Then yoy may add any formula you need: β€œ\displaystyle\sum_{i=0}^{n}”. But if you just need a small sign you can also copy and past it from HTML Character Entity Reference Chart.

It’s easy!
