Summing Up

Mathematical Mentalism Calculator

Generate number combinations for "sum to" mentalism effects

How it works:

  1. Enter a target number (5-7 digits)
  2. Choose group size (3 or 4 numbers)
  3. Algorithm finds combinations that sum to your target
  4. Use the generated numbers in your mentalism routine

5–7 digits (for example 125000).

Enter the group size (3 or 4):
Algorithm Quality:

Thorough mode provides better randomization for more convincing effects
