When using the symbols for less than and greater than in mathematical expressions, one must understand their specific meanings and rules for usage.

These symbols have specific implications that must be followed to ensure accurate mathematical communication.

**Here are some important rules to keep in mind:**

- The symbol “<” represents “less than” and is used to compare two quantities, with the smaller quantity on the left and the larger quantity on the right.
- The symbol “>” represents “greater than” and is used to compare two quantities, with the larger quantity on the left and the smaller quantity on the right.
- When comparing quantities, it’s essential to ensure that the direction of the symbol points towards the smaller quantity.
- In equations, the symbols must be used with precision to accurately represent the relationship between the quantities involved.

### Comparing Numbers Using Symbols

In comparing two quantities, the symbol ‘<’ denotes that the quantity on the left is less than the quantity on the right, while the symbol ‘>’ indicates that the quantity on the left is greater than the quantity on the right. For instance, if we have 5 < 8, it means that 5 is less than 8.

Similarly, if we have 10 > 3, it means that 10 is greater than 3. Understanding these symbols is crucial for comparing numbers and quantities in mathematics.

It enables us to express relationships between different values and make meaningful comparisons.

Mastering the rules for using less than and greater than symbols is fundamental for interpreting and solving mathematical problems.

### Inequality Signs in Math

The application of inequality signs in mathematics involves precisely defining the relationships between numbers and quantities using the symbols ‘<’ and ‘>’. Understanding these symbols is crucial for comparing and ordering numbers.

**Here are some key points to consider:**

- The ‘<’ symbol represents “less than” and the ‘>’ symbol represents “greater than”.
- When comparing two numbers, the open side of the symbol always points to the smaller number.
- Inequality signs are used to express the relationship between two quantities, indicating which one is smaller or greater.
- In mathematics, the use of inequality signs is fundamental for expressing numerical relationships in equations and inequalities.

Understanding the rules for using these inequality signs is essential for solving mathematical problems and making accurate comparisons.
