The default math editor has some basic math functions and if you know LaTex, you can write your own equations by clicking “Switch to Advanced.” The default math editor is missing some important math notation (such as limits and integrals). If this one does not do all the things you want it to do, consider adding the MathType App described below.
MathType App
You can add an additional math equation editor called MathType that has more notation. MathType also supports LaTex.

Click on MathType, then click +Add App and finally Add App to install it
