here is how it is without using displaystyle:

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?

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*}
