How can I write the letter, capital sigma, to represent it as 'The sum of'? Also, is it possible to take picture of my problem and post my question for help?

\[\sum_{?}^{?}\] Use the equation editor. And yes you can take pictures.

Also if anyone posts anything that looks interesting you can right click it and "show math as" "TeX commands" and see how they did it.
