Question 25

In this cryptarithm, different letters stand for different digits:
$$\begin{array}{rrrrr}&C&O&O&L\\+&M&A&T&H\\\hline S&A&S&M&O\end{array}$$
Given M=7, find $S+A+S+M+O$.

Interpretation: Leading letters C, M and S are nonzero; other letters may represent 0 if all constraints permit it.

Answer format: an integer without units. Leading zeros are optional; the source uses four digit boxes.
