what is an inequality?

http://en.wikipedia.org/wiki/Inequality

An inequality is a mathematical statement that compares two different quantities and indicates their relative size or order. It expresses that one quantity is greater than, less than, or equal to the other.

To understand inequalities, it's helpful to have a basic understanding of mathematical symbols:

1. Greater than (>): This symbol ">" represents that the value on the left side of the symbol is larger than the value on the right side. For example, 5 > 3 indicates that 5 is greater than 3.

2. Less than (<): This symbol "<" represents that the value on the left side of the symbol is smaller than the value on the right side. For example, 2 < 4 indicates that 2 is less than 4.

3. Greater than or equal to (≥): This symbol "≥" represents that the value on the left side of the symbol is greater than or equal to the value on the right side. For example, 5 ≥ 5 indicates that 5 is greater than or equal to 5.

4. Less than or equal to (≤): This symbol "≤" represents that the value on the left side of the symbol is less than or equal to the value on the right side. For example, 3 ≤ 3 indicates that 3 is less than or equal to 3.

Inequalities can be used with variables as well. For example, we can have an inequality like "x > 2," where x represents any real number greater than 2. Inequalities are commonly used in algebra, calculus, and real-world applications to describe relationships between quantities.
