In mathematics, the absolute value of a number is the non-negative value of that number, regardless of its sign. Graphing calculators are powerful devices used for plotting graphs, solving equations, ...

Understanding the concept of absolute values is vital for tackling algebraic equations and evaluating various mathematical expressions. The absolute value of a number is the distance from zero on the ...

This ARC aims to create contexts for students to experience a variety of visual representations that reinforce the definition of absolute value. Explorations connecting back to elementary concepts and ...

Abstract: This paper gives a novel generalized absolute value representation of two-dimensional continuous piecewise-linear (PWL) functions, which is obtained by analyzing the fundamental structures ...

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 ...
