Writing math on the web can be difficult -- not on Authorea!
Writing equations online can be very painful. While there are many options out there for writing simple math equations, none of them provides as many options as Authorea.
How Authorea helps you write math
In Authorea, you have a few different choices for writing math. You can use the built-in Equation Editor (\ref{940296}), or the built-in LaTeX Editor (\ref{896173}). The Equation Editor has two ways to write equations: using the Live Editor and using the TeX source.
