I want to be able to create many equations, say $a+b=c$ and $c+d=e$, save the equation as a variable but not have the equation be displayed. I simply want to have the ability to use the label/variable name(or perhaps another term?) to display them at a later point in the document. This is because the order of the equations will change later and I want to be able to easily move them around.
Essentially I want to see if I can define hidden variables that take theses equations and display these "variables" later in the document
