The Puzzle
Solve the following (each letter is a digit):
CAT = (C + A + T) × C × A × T
CAT = (C + A + T) × C × A × T
The Solution
135 = (1 + 3 + 5) × 1 × 3 × 5
If you allow A=T, then another solution is:
144 = (1 + 4 + 4) × 1 × 4 × 4
If you allow A=T, then another solution is:
144 = (1 + 4 + 4) × 1 × 4 × 4
