is always greater than or equal to zero.Mathematically, it is defined as:
: In physics and chemistry, absolute value is used to define "margins of error" or tolerances (e.g., is always greater than or equal to zero
The study of absolute value and intervals is not merely an abstract exercise but a tool for precision. By converting distances into sets of numbers (intervals), students gain a geometric intuition for algebra that serves as a foundation for more advanced calculus and analysis in later academic years. is always greater than or equal to zero
