basic algebra visualization
basic algebra visualization: ”

a set of visuospatial illustrations demonstrating some interesting properties of numbers, such as that (n+1)×(n-1)=n2-1, that the perfect squares (0,1,4,9,…) go up by successive odd numbers (1,3,5,…), & that the area of a triangular number (1+2+…+n) has a closed form. these properties are easy to show using algebra, but make more sense when visualized.
