Study Notes
Number Systems: A Foundation in Math and Daily Life
- Number systems are fundamental for representing quantities, enabling precise expression in various contexts (e.g., counting apples, measuring distances).
Mathematical Concepts and Applications
- All mathematical concepts and formulas stem from the number system.
- From basic arithmetic to advanced mathematical fields, numbers are essential for reasoning and problem-solving.
Types of Numbers
- Counting Numbers: Positive integers starting from 1 (1, 2, 3...).
- Whole Numbers: Counting numbers plus zero (0, 1, 2...).
- Integers: Positive and negative whole numbers including zero (-3, -2, -1, 0, 1, 2, 3...).
- Rational Numbers: Numbers expressible as fractions (e.g., 3/4, -2/5).
- Irrational Numbers: Numbers not expressible as fractions (e.g., √2, π).
- Real Numbers: The combination of rational and irrational numbers.
- Even Numbers: Divisible by 2 (e.g., 2, 4, 6...).
- Odd Numbers: Not divisible by 2 (e.g., 3, 5, 7...).
- Prime Numbers: Divisible only by 1 and themselves (e.g., 2, 3, 5...).
- Composite Numbers: Having multiple factors (e.g., 4, 6, 8...).
Digital Systems and Representation
- Number systems are crucial for digital systems due to their use of binary representation (base-2).
- Computers utilize bits (0s and 1s) to process information based on number system principles.
