In mathematics, a quantity is a property that can exist in multiple amounts or numbers. It can be measured and expressed with a numerical value.

**Discrete Quantity:**These are countable quantities that can only take specific values (e.g., the number of students in a class).**Continuous Quantity:**These are measurable quantities that can take any value within a given range (e.g., the height of a person).

Quantities are often associated with units of measurement, which provide a standard for comparison. Common units include meters, kilograms, liters, seconds, etc.

Basic mathematical operations such as addition, subtraction, multiplication, and division can be performed on quantities.

1. The length of a table is 2 meters (a continuous quantity).

2. There are 25 students in a class (a discrete quantity).

3. A car travels at a speed of 60 kilometers per hour (a continuous quantity).

- Understand the difference between discrete and continuous quantities.
- Practice converting quantities between different units of measurement.
- Solve word problems involving quantities and their operations.
- Explore real-life examples of quantities in various contexts (e.g., time, distance, volume).

Quantities are fundamental in mathematics and the real world, representing measurable properties that can be compared and operated upon using mathematical operations and units of measurement.
