Inequality Symbols and Definitions
Inequality Symbols and Definitions is a Grade 7 math skill from Big Ideas Math, Course 2, covering Inequalities. An inequality is used in algebra to compare two quantities that may have different values. We use inequality symbols to show these relationships: is read is less than is read is greater than is read is less than or equal to is read is greater than or equal to Explanation These inequality symbols are used to compare values and show relationships between quantities.
Key Concepts
An inequality is used in algebra to compare two quantities that may have different values. We use inequality symbols to show these relationships: $a < b$ is read $a$ is less than $b$ $a b$ is read $a$ is greater than $b$ $a \leq b$ is read $a$ is less than or equal to $b$ $a \geq b$ is read $a$ is greater than or equal to $b$.
