Modulus Inequality
What is Modulus Inequality?
A modulus inequality asks for every value of the variable whose distance from a fixed point satisfies a size condition. A 'less than' condition describes a single band centred on that point, while a 'greater than' condition describes the two outer rays that lie beyond it. The endpoints are included when the inequality is inclusive and excluded when it is strict, and any non-modulus side containing the variable must first be required to be non-negative.
