Every math student learns a magical mathematical formula that goes something like this: “Negative B Plus or Minus the Square Root of …“. We’ll take a look at this formula from some unusual angles (e.g., from upside down…). Math Circle OnlineSunday March 21, 2020 1:00-2:30PMFree of charge Look for login instructions in your email.
Let’s take look at straight lines from a new perspective. We’ll see that the basic building blocks of geometry – points and lines – are really not all that different. Then we’ll take a brief visit to infinity (and beyond). Join us for an online session of the Math Circle. When: Saturday March 14, 10:00 …
The Math Circle resumes this weekend for the topic: “Monday is One Day”. My birthday was on a Monday this year – I really hate that… but it will be on a Saturday in 2024 – much nicer! Following the approach of mathematician John Conway, we will learn how to apply modulo 7 mental arithmetic …
Please join us as the Math Circle meets this Saturday to consider Arithmetic Without Numbers. We’ll learn how to add, subtract, multiply, divide, and take square roots, without writing down any numbers or calculations. We’ll just use a piece of wood and a bit of string, along with an all-time classic math book. When: Saturday …
The Math Circle convenes this Sunday to consider the Case of Squares and Primes. You know what square numbers are, and you know what prime numbers are. Curious patterns emerge when we look at the differences between them. To help us deduce the facts of the matter, we may call upon the help of a …
The Math Circle kicks off the spring term… Don your Sola Topee as we conduct an archeological/mathematical exploration of ancient Mesopotamia. Join us at the Math Circle: Nashua Public LibrarySaturday January 11th 9:30-11:30AMFree of charge
What makes a snowflake look like a snowflake? What’s a snowfake? And most importantly, do you know the difference? Join us at the Math Circle: Hollis Social LibrarySunday December 15 2:00-4:00PMFree of charge
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
There’s more than one way to multiply! We’ll look at three methods different from the one you learned in school, invented in ancient times (2000BC, 1600BC, 1960AD). Then we will discuss a new method invented in March 2019 by a pair of mathematicians from France and Australia. Math CircleNashua Public LibrarySaturday November 2 9:30-11:30AMFree of …
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
