Logical Arithmetic

What math can we do with only two numbers? We are going to investigate and apply modulo two arithmetic. If you’re unfamiliar with this, it might sense to study the addition and multiplication tables for mod 2 beforehand, and commit them to memory: Math CircleNashua Public LibrarySaturday November 23 9:30-11:30AMFree of Charge

Multiplication is like Addition

This week, the Math Circle is going to do an in depth study of addition and multiplication tables, mostly single digit numbers, in a way you probably haven’t seen before. No calculators required, so be prepared to do some mental arithmetic! Math CircleNashua Public LibrarySaturday October 12 9:30-11:30AMFree of Charge

Dice Polynomials

This week, we will investigate Dice Polynomials. We can represent ordinary dice by polynomials. Those polynomials may tell us something about dice that we might not already know. We’ll finish by using our dice polynomials to make some dice you have never seen before. Math CircleNashua Public LibrarySaturday October 5 9:30-11:30AMFree of Charge
