    how do i make things bigger?

    for example, i am trying to make the parantheses around 1/2 bigger using the \displaystyle code.

    here is how it is without using displaystyle:

    code: [tex] \sum_{x=1}^{\infty}(\frac{1}{2})^n [ /tex]
     \sum_{x=1}^{\infty}(\frac{1}{2})^n

    with displaystyle

    code: [tex] \sum_{x=1}^{\infty}\displaystyle{(}\frac{1}{2}\dis playstyle{)}^n [ /tex] (i didnt put a space or anything in displaystyle, but it is showing up like that for somereason...)
     \sum_{x=1}^{\infty}\displaystyle{(}\frac{1}{2}\dis  playstyle{)}^n

    I use \left ( and \right ).
    [tex] \sum_{x=1}^{\infty} \left ( \frac{1}{2} \right )^n [/tex] \implies  \sum_{x=1}^{\infty} \left ( \frac{1}{2} \right )^n

    kk i also just say that some people use \big and \bigg. are there any advantages of \left and right? left and right only work for paranthesesi right?

    Re: how do i make things bigger?

    No, left and right work for anything. This is the command to use so that the compiler will scan the size of what is inside it and choose the appropriate size for what is surrounding it. For example...

    \left[ \begin{matrix} a & b & c \\ d & e & f \\ g & h & k \end{matrix} \right]

    gives

    $\displaystyle \begin{align*} \left[ \begin{matrix} a & b & c \\ d & e & f \\ g & h & k \end{matrix} \right] \end{align*}$
