Absolute value is the non-negative value of a number without regard to its sign. Absolute value is distance from zero along the real number line. Real absolute value is continuous, differentiable except at x=0. Absolute value has four fundamental properties: non-negativity, positive definiteness, multiplicativity, and subadditivity
Absolute value determines magnitude of objects regardless of direction. Real numbers have only two directions: positive or negative. Absolute value is piecewise function: returns same for positive, flips for negative. Absolute value of vectors equals their length using Euclidean norm
Absolute value represents a number's distance from the origin 0. It is denoted by |x| or 'mod x', pronounced as 'modulus of x'. Absolute value is always non-negative
Zero is an integer, but neither positive nor negative. Zero is a whole number without fractions or decimals. Zero sits between positive and negative numbers on the number line
Absolute value shows distance from 0 on number line. Absolute values are never negative. For vectors, absolute value equals magnitude. For complex numbers, absolute value is distance from origin
Absolute value is a number's distance from zero on the number line. Absolute value is always positive. Negative numbers' absolute value is their positive version
