<p>Puzzles like this are called <i>cryptarithms</i> or <i>alphametics</i>. The letters spell out actual words, but if you replace each letter with a digit from <code>0&ndash;10</code>, it also &#8220;spells&#8221; an arithmetic equation. The trick is to figure out which letter maps to each digit. All the occurrences of each letter must map to the same digit, no digit can be repeated, and no &#8220;word&#8221; can start with the digit 0.
