Counting in balanced ternary, from Michael Stifel's Arithmetica Integra, published in 1544. This is part of a general discussion of manipulation of numbers as sums of elements in a geometric series.

The next chapter describes algorithms for computing square roots, cube roots, and so on. A modern formulation of Stifel's algorithms would involve binomial coefficients, so of course Stifel provides a handy illustration of "Pascal's" triangle.

I had to reconstruct this gif by Bill Gosper in GeoGebra to believe it.

An unusual cubic representation problem
Article by Andrew Bremner and Allan Macleod
In collection: Puzzles
For a non-zero integer \(N\), we consider the problem of finding \(3\) integers \( (a, b, c) \) such that \[ N = \frac{a}{b+c} + \frac{b}{c+a} + \frac{c}{a+b}. \] We show that the existence of solutions is related to...
