Define a new environment based on “proof”
2
I want to change the word "Proof" as in begin{proof}...end{proof} to "Solution". I found out that begin{proof}[Solution]...end{proof} could do the trick. But is there a way to define a new environment begin{solution}...end{solution} to make it automatic. I only need to change the word "Proof -> Solution". Everything else should stay the same. documentclass{article} usepackage[utf8]{inputenc} usepackage[english]{babel} usepackage{amsthm} newtheorem{theorem}{Theorem} begin{document} begin{theorem} $A^2=B^2+C^2$ end{theorem} begin{proof} $A=1, B=1, C=0$ end{proof} begin{theorem} $D^2=E^2+F^2$ end{theorem} begin{proof}[Solution] $D=1, E=1, F=0$ end{proof} end{document}
