The 84% Method: A Terminal-Digit Selection Heuristic for Two-Digit Mental Multiplication
The 84% Method is a selection heuristic for two-digit mental multiplication. It classifies a factor as favorable when its units digit is 0, 1, 2, 5, 8, or 9. Under uniformly distributed terminal digits, the probability that at least one of two factors is favorable is 1 − (4/10)²...
