plain-language theorem explainer

The equality 101 = 1² + 10² holds in the natural numbers. Number theorists checking small primes that are sums of two squares may cite this instance when verifying quadratic representations. The proof proceeds by direct evaluation via native_decide.

Claim. $101 = 1^2 + 10^2$

background

The module supplies lightweight wrappers around Mathlib arithmetic functions, beginning with the Möbius function μ. Local conventions treat statements as footholds for later Dirichlet inversion without heavy algebraic machinery. No upstream lemmas are referenced for this identity.

proof idea

The proof is a one-line wrapper that applies native_decide to confirm the numerical equality.

why it matters

This supplies a concrete numerical check inside the arithmetic functions module. It may anchor small-case verifications for sums of squares among primes. No downstream theorems depend on it according to the used_by relations.
