The atoms of multiplication

Why does this exist?

Every natural number breaks into primes in exactly one way — and that uniqueness quietly protects your credit card.

Part of the Journey of Numbers How much is there — and how do we write it down?

🔬 This lab is being built

When it opens, it will follow the same flow as every MathIsland lab:

  1. 1An opening question — the problem this concept solves
  2. 2Why it was needed — where the old tools failed
  3. 3Hands-on experiment — sliders, simulations, direct play
  4. 4Common misconceptions, broken
  5. 5The idea, written as mathematics
  6. 6Where you meet it in real life
  7. 7Connections to the previous and next concepts
