Study Notes
Sets in Mathematics
- A set is a collection of unique objects, known as elements or members, that can be anything (numbers, letters, people, etc.).
- Mathematicians define sets very carefully to ensure that they are well-defined and can be used as a foundation for more complex mathematical concepts.
Prime Numbers
- A prime number is a positive integer that is divisible only by itself and 1, making it a fundamental building block of arithmetic.
- Prime numbers go on forever, meaning that there is no largest prime number, and new ones can always be found.
Sets and Numbers
- Sets contribute to defining numbers and operations in mathematics by providing a framework for working with collections of objects and manipulating them using set operations (e.g., union, intersection, complement).
Quadrilaterals
- The sum of the interior angles of a simple quadrilateral is 360 degrees.
- A convex quadrilateral has interior angles that are all less than 180 degrees.
- The Latin word for 'side' in the term 'quadrilateral' is 'latus', meaning 'side'.
- The term 'gon' in the context of 'quadrilateral' means 'angle' or 'corner'.
- A quadrilateral is also referred to as a tetragon, which is a type of polygon with four sides.
