Inequality notation is used in mathematics to describe the relationship between two quantities or expressions

Inequality notation is used in mathematics to describe the relationship between two quantities or expressions. It helps express if one quantity is greater than, less than, or equal to the other.

There are four main inequality symbols used in notation:

1. Greater than: denoted by the symbol “>”, it indicates that the quantity to the left of the symbol is greater than the quantity to the right. For example, 5 > 3 means that 5 is greater than 3.

2. Less than: denoted by the symbol “<", it indicates that the quantity to the left of the symbol is less than the quantity to the right. For example, 2 < 6 means that 2 is less than 6. 3. Greater than or equal to: denoted by the symbol "≥", it indicates that the quantity to the left of the symbol is greater than or equal to the quantity to the right. For example, 4 ≥ 4 means that 4 is greater than or equal to 4. 4. Less than or equal to: denoted by the symbol "≤", it indicates that the quantity to the left of the symbol is less than or equal to the quantity to the right. For example, 7 ≤ 7 means that 7 is less than or equal to 7. In addition to these symbols, inequality notation can also include variables, constants, and algebraic expressions to represent a broader range of relationships. For example, x > 2 means that x is greater than 2, where x can take any value that is larger than 2.

Inequality notation is widely used in algebra, calculus, and other branches of mathematics to compare and describe relationships between quantities. It is particularly useful in representing ranges of values and solving equations and inequalities.
