Why "Commutative Property" Is Your Best Friend (e.g., 20+5 vs 5+20)

Math lets you swap things around. Use this to your advantage to test multiple positions with a single logic.

AI Summary

This logic guide explains how A+B=C is the same as B+A=C. If you know "2" and "5" are in the sum but don't know the order, checking one order gives you clues about the other. It also warns that subtraction and division are NOT commutative.

AI Highlights

  • Flexible Slots: If 3+4 is wrong, try 4+3 next.
  • Purple Clues: Commutativity is the main reason you see purple tiles for operators or operands.

Swapping for Science

If you have a green "7" result but purple "3" and "4", you solve it instantly: swap them.

Watch Out for Minus

Remember: 5-2 is NOT 2-5. Commutativity only works for + and *.
