An algebraic number is a number that is a root of a non-zero polynomial with integer coefficients. It is well-known that the sum of two algebraic numbers is algebraic. In particular, the sum of a list of square roots of integers is algebraic. In this challenge, you are given a list of distinct po...

Is there a chance to get a staging ground for other sites on the network? Some, like Code Golf and Worldbuilding have hacked together "sandboxes" on their Meta sites, but it is hard to get newcomers to notice and use them, and the "technology" (Meta post which can grow to have thousands of answer...

The sequence of Harmonic numbers are the sums of the reciprocals of the first N natural numbers (not including zero): \${\displaystyle H_{n}=1+{\frac {1}{2}}+{\frac {1}{3}}+\cdots +{\frac {1}{n}}=\sum _{k=1}^{n}{\frac {1}{k}}.}\$ Your task is to implement the sequence of numbers a(n) = the smalle...
