What are some fun math problems with integer answers from 0-18?
The Penguin Dictionary of Curious and Interesting Numbers has a fun microfacts you could build on.
The smallest right triangle am I (integral sides, area = 6). For any number, of squares at least you must have me. (Any positive integer can be represented as the sum of at most 4 squares of other integers.) The square of a cube and the cube of a square; I am the smallest– divided by as many colors as National Geographic will ever need (64/4 = 16). If chaos is your aim, equations and variables as many as I am are all that you require. (3 variables and 3 equations with some nonlinearity are enough for chaos.
