ABSOLUTE VALUES IN DISTANCE

Vocabulary practice cards covering the definitions, notation, and properties of absolute value as presented in the lecture notes.

Absolute Value

The distance of a number from zero on the number line.

$$|x|$$

The mathematical notation used to represent the absolute value of a number.

Non-negative

A key property of absolute value, indicating it is never negative.

Opposite numbers

Numbers that have the same absolute value because they are the same distance from zero on the number line.

Distance between two numbers $a$ and $b$

The calculation of distance on a number line represented by the formula $|a - b|$.

Numerical Example: Distance between $-2$ and $6$

A specific calculation resulting in a distance of $8$, calculated as $|6 - (-2)|$.
