Some visualizations in elementary number theory:

• • Multiplication tables modulo n
  • Modular Dynamics
  • Diffie-Hellman visualized
  • Ratios and the Chinese Remainder Theorem
  • Geogebra Notebook showing rational rays (relates to Farey fractions)
  • Euler’s Totient (phi) Function (proof without words that it is multiplicative)
  • Quantum Fourier Transform
  • Shor’s Algorithm
