Page 1: Introduction to Natural Numbers and Number Types
This page introduces the concept of liczby naturalne naturalnumbers and various types of numbers. Natural numbers are defined as the set N = {0, 1, 2, 3...}. The page then delves into even and odd numbers, providing algebraic representations for each.
Definition: Liczby naturalne (Natural numbers) are the set of numbers including 0, 1, 2, 3, 4, and so on.
Example: Even numbers are represented as 2k or 2n, while odd numbers are represented as 2k+1 or 2n+1.
The page also introduces liczby pierwsze (prime numbers) and liczby złożone (composite numbers). Prime numbers are defined as having exactly two divisors, while composite numbers are all numbers greater than 1 that are not prime.
Highlight: Prime numbers have exactly two divisors, for example, 2, 3, 5, 7, etc.
Lastly, the page introduces the concepts of NWW (najmniejsza wspólna wielokrotność - least common multiple) and NWD (największy wspólny dzielnik - greatest common divisor). An example calculation for NWD132,360 = 12 and NWW132,360 = 3960 is provided.
Example: The calculation of NWD132,360 = 2 * 2 * 3 = 12 and NWW132,360 = 2 * 2 * 3 * 11 * 2 * 3 * 5 = 3960 demonstrates the process of finding these values.
