Absolute value equations (AVEs), characterised by the inclusion of absolute value functions in the variables, present inherently non‐smooth and computationally challenging problems that are often ...

Absolute value is a mathematical concept often used in conjunction with a number line or graph to represent the relative value from zero (modulus). To illustrate this idea in a different way, the ...

An equation is formed by an expression either side of an equals sign, the left hand side is equal to (i.e. has the same overall value) as the right hand side. The key to dealing with equations is to ...
