Are there really primitive tribes whose system of counting goes: One, Two, Many, ... indicating that from three on it's more or less a blur? Maybe we modern humans are such a tribe. Despite the sophistication we see in ourselves compared with our less advanced ancestors from times long past, it's surprising how little progress we've made in addressing some basic problems in 3D or beyond, or when solving seemingly simple equations in ≥3 variables. ​We'll survey a dozen fun topics in shapes and numbers and patterns whose basics and generalisations can be explored with little mathematical background, and which speedily lead to ``what if?'' questions ranging from easy to tricky to ``we just don't know.'' ​ Fruit, cakes, doughnuts, bagels, coins, boxes, cubes, primes, squares, and​ sums involving powers will all make appearances. Once or twice we will stray into deeper waters and touch on more sophisticated topics.
