Answer – The four inequality notations are <, >, ≤, and ≥.
Explanation:
Inequalities, as the name implies, indicate the relation between two unequal numbers or algebraic expressions. Unlike in equations where the two sides are equal, inequalities represent a comparison between the two sides.
The short-hand symbols used to show these comparisons are called inequality notations and include the following:
1. <, meaning less than
2. >, meaning greater than
3. ≤, meaning less than or equal to
4. ≥, meaning greater than or equal to
While using any of the above inequality notations, the smaller value is placed next to the narrow end and the larger value is marked by the wider end: small < LARGE.
