Pass Check: Inequalities
Inequalities compare expressions using <, >, ≤ or ≥ instead of an equals sign.
Inequality
A statement comparing two expressions using <, >, ≤ or ≥.
Strict inequality
An inequality using < or > (does not include equal values), shown with an open circle on a number line.
Inclusive inequality
An inequality using ≤ or ≥ (includes equal values), shown with a closed circle on a number line.
Integer solution
