# Mathematics ## Types - Arithmetic: Basic number operations - Algebra: Symbols and rules for manipulating them - Geometry: Shapes, sizes, and spatial reasoning - Trigonometry: Relationships in triangles - Calculus: Change and motion (includes differential and integral calculus) - Number Theory: Properties of integers - Set Theory: Study of sets (collections of objects) - Linear Algebra: Vector spaces and linear equations - Analysis ## Prime Numbers A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 ## Fibonacci Sequence The Fibonacci sequence is a sequence of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1.
