Latex sum convention

[mathematic]

Whenever I write a sum in Latex, the limits appear forward of the sum sign.  I have seen many instances where the limits are below and above.  What is the code to get them there?

I have removed the beginning and end square brackets to show the coding.

math]\sum\limits_{n = a}^{n = b} {{n^2}} [/math

[math]\sum\limits_{n = a}^{n = b} {{n^2}} [/math]

 

math]\sum\nolimits_{n = a}^{n = b} {{n^2}} [/math

[math]\sum\nolimits_{n = a}^{n = b} {{n^2}} [/math]

Today I learned!

 

Another way is math]\displaystyle e^z = \sum_{n=0}^\infty \frac{z^n}{n!}[/math

[math]\displaystyle e^z = \sum_{n=0}^\infty \frac{z^n}{n!}[/math]
