Real numbers are a fundamental part of mathematics, and several key operations can be performed on them. The main operations include:
- Addition: Combining two real numbers to get a sum. For example, 3 + 5 = 8.
- Subtraction: Finding the difference between two real numbers. For instance, 10 – 4 = 6.
- Multiplication: Calculating the product of two real numbers. For example, 7 x 6 = 42.
- Division: Determining how many times one real number is contained within another. For instance, 20 ÷ 4 = 5. Note that division by zero is undefined.
These operations can also be applied in various combinations to perform more complex calculations. Understanding these operations is essential for solving mathematical problems and for applications in real-life situations.
