🔢 Number theory fact
The Generators of Modular Arithmetic
In number theory, a primitive root of a number $n$ is a value that can generate every other number coprime to $n$ through successive powers. Think of it as a 'master key' that, through repeated multiplication, can unlock every possible remainder in a modular system. This property is a fundamental building block for modern encryption algorithms used to secure your data.
