I know
\begin{equation*} \end{equation*} doesn't number my equation, but even though that's true for equations, I am unable to use it for Axioms, where I have included the environment as
\newtheorem{axiom}{Axiom}
and adding * after the argument of \begin{} \end{} class doesn't remove the numbering, and also \nonumber doesn't do it as well.
Can someone please point me out what is simple possible solution of this?
