Daniel Mentrard, Ronan Downes, 2020. 3. 11.

Visualizations of algebraic relations of binomial formulas, of literal development and of distributivity under puzzles of geometric shapes


  • 1. Distributivity
  • 2. Algebraic puzzle: development
  • 3. Simple distributivity
  • 4. (a - b)²
  • 5. Proof without words : a²-b²
  • 6. Proof without words : a²- b²
  • 7. (a+b)²=a²+2ab+b²
  • 8. (a + b +c )²=a²+b²+c²+2ab+2ac+2bc
  • 9. Proof without words : difference a^3 - b^3
