About the number theory toolkit
The number theory toolkit handles the building blocks of whole-number math: prime factorization (factor trees), greatest common divisor (GCD) and least common multiple (LCM), divisibility checks, base conversion, and modular arithmetic.
Each result comes with the steps, so the toolkit doubles as a way to learn the method, useful for fractions, ratios, and early algebra.
