CASSATT + CEZANNE + MANET = MATISSE
What is this puzzle?
Solve the addition alphametic puzzle where CASSATT + CEZANNE + MANET = MATISSE. Each letter represents a unique digit from 0-9. No number starts with zero.
Difficulty: hard · Category: addition · Unique letters: 9
This hard-level addition alphametic puzzle features 9 unique letters (A, C, E, I, M, N, S, T, Z). In the equation CASSATT + CEZANNE + MANET = MATISSE, each letter maps to a distinct digit from 0 to 9. With only 9 of 10 digits used, 1 digit remains unused in the solution. The leading letters C and M cannot represent zero — this is your first constraint. This puzzle has 3 addends (CASSATT + CEZANNE + MANET), making carry analysis more complex. Start from the rightmost column and work left, tracking carries between columns. This is a challenging puzzle that requires systematic use of carry analysis, parity checking, and elimination. Start by listing all constraints, then methodically eliminate impossible digit assignments.
- This addition alphametic has 9 unique letters to determine.
- Leading letters: C, M. None of these can be zero.
- There are 9 unique letters, so 1 digits from 0–9 will not be used.
- Start from the rightmost column (units place) and work left, tracking carries between columns.
- With three addends, each column can produce a carry of at most 2.
- With many unique letters, use elimination and constraint tracking to narrow down possibilities step by step.
