You can add a new file with \\ at the end of the line

  • This must be inside a math environment like $ $, \[ \] or equation

Aligning Multiple Equations

We have seen many ways to write equations, but Just one equation what if you want to write 5 equations, or more than 5 equations? Do we need to put each equation in \[\] it is going to be a nightmare!!

There exist an environment, the gather environment this centers a group of formulas on a separate line
