Study Notes

  • Mathematics is the abstract science of number, quantity, and space
  • It can be studied in its own right (pure mathematics) or as it is applied to other disciplines such as physics and engineering (applied mathematics)

Arithmetic

  • Arithmetic deals with operations on numbers
  • Basic operations: addition, subtraction, multiplication, and division
  • These operations are the foundation for more advanced mathematics

Algebra

  • Algebra extends arithmetic by using letters (variables) to represent numbers
  • It enables the formulation of general relationships and the solving of equations
  • Key concepts include: expressions, equations, inequalities, and functions

Geometry

  • Geometry is concerned with the properties and relations of points, lines, surfaces, and solids
  • Euclidean geometry is based on a set of axioms and deals with shapes in a two-dimensional plane and three-dimensional space
