Is asking your youngster to study math like asking him to eat Brussels sprouts? Then there’s no need to let him in on the secret that he’s actually learning with math games. From arithmetic to ...

Modular arithmetic utilizes this "wrapping around" idea, after you reached the greatest element comes the smallest. So modular arithmetic is a sort of a mindset. A binary operation is an operation which combines two elements, for example addition is a binary operation since it combines two elements.
A famous theorem by¹ Fermat is that four squares cannot form an arithmetic progression. (Three definitely can: $1^2 = 1$, $5^2 = 25$ and $7^2 = 49$ already give an example). It already has been dis...
- does the proof above make sure that $a_n$ is not arithmetic? a sequence cannot be arithmetic and geometric at the same time, right? 2) what about more complex expressions? like $b_n=ln (n)$? how do I quickly see if it is arithmetic or geometric sequence?
It’s well known that the geometric mean of a set of positive numbers is less sensitive to outliers than the arithmetic mean. It’s easy to see this by example, but is there a deeper theoretical reas...
There's more to say about three-term arithmetic progressions of squares, but first a review of Pythagorean triples, which turn out to be closely related to, but better studied than, three-term arithmetic progressions of squares.
