Alphametic is a puzzle that involves replacing letters with digits and solving an arithmetic equation. Some synonyms for alphametic include cryptarithm, verbal arithmetic, and numerical puzzle. These types of puzzles can be challenging but also fun and rewarding when solved. Cryptarithms are often used in math competitions, brain teasers, and educational settings to teach problem-solving skills and logic. Verbal arithmetic is another name for these puzzles because the equations are written out in words rather than symbols. Whatever you call them, alphametics are a great way to exercise your brain and challenge yourself.
