The fundamental mathematical operations applicable to number systems are addition, subtraction, multiplication, and division.
These four operations are the building blocks for more complex mathematical calculations within any number system, including but not limited to:
- Addition: Combining two or more numbers to find their total sum.
- Subtraction: Finding the difference between two numbers.
- Multiplication: Repeated addition of a number to itself a specified number of times.
- Division: Splitting a number into equal parts.
These operations can be performed across different number systems like binary, decimal, hexadecimal etc. with adjustments to the base of the number system taken into account.
