\[ \begin{array} {ccccc} \large & & \color{red}M & \color{green}A & \color{blue}R & \color{purple}T\\ \large + & &\color{purple}T & \color{blue}R& \color{green}A & \color{red}M \\ \hline \large & & \color{blue}R & \color{green}A & \color{red}M & \color{green}A \end{array} \]
If each letter represents a different nonzero digit, what is \(\color{red}M\color{black}?\)
Another tough, algebraic cryptogram puzzle!
