I just added an update to the campaign that links math circle materials with some of mathematical pathways that start with Farzanah's puzzle: Egyptian fractions, continued fractions, Fibonacci numbers, and greedy algorithms. There's a lot of rich mathematics to explore.
That's the first time *I* hear about it for sure. It's funny because it's true.
I don't like how "dx" (or other such) at the end of integration visually blends into the formula being integrated. That info should come before you start integrating, anyway, not at the end. And if there's one variable? That one variable should be the default for integration without mentioning it!
In many cases, it's easier with INFINITELY many: aimathcircles.org/issue-52-a-s...
We hear about Natural Math books at San Francisco Bay math circles, war refugee classes in Europe, Indigenous summer math camps, and rural schools in Nepal and Tanzania. Antarctica is the only continent we haven't reached (yet). Thank you for your support!(5/5)
CHARITABLE MATH - Do good and make a Creative Commons mathematics book openly accessible to thousands of learners around the world. Support an awesome author and a small indie publisher. (4/5)
DEDICATION - Put your name, company's name, a wish, or a dedication to friends or family on the book's thank-you page. This makes for a unique gift or a gift to yourself. One could help a child to contribute $1 for a fun opportunity to see their name in the book's credits. (3/5)
BOOK - Preorder a copy of the book and be one of the first in the world to read it with your children or students. (2/5)
