Study Notes
Introduction to Real Numbers
- Continued exploration of real numbers and irrational numbers.
- Focus on two key properties of positive integers: Euclid's Division Algorithm and the Fundamental Theorem of Arithmetic.
Euclid's Division Algorithm
- States that any positive integer a can be divided by another positive integer b with a remainder r smaller than b.
- Represents the standard long division process.
- Important for understanding divisibility properties of integers.
- Utilized mainly to compute the Highest Common Factor (HCF) of two positive integers.
Fundamental Theorem of Arithmetic
- Asserts every composite number can be uniquely expressed as a product of prime numbers.
- Simple to comprehend but has profound implications in mathematics.
- Used to prove the irrationality of certain numbers such as √2, √3, and √5.
- Helps determine the nature of the decimal expansion for rational numbers of the form p/q, with the prime factorization of q revealing key insights.
