    Key Areas of Mathematics

    Arithmetic

    • Fundamental operations include addition, subtraction, multiplication, and division.
    • Types of numbers encompass whole numbers, integers, rational numbers, and irrational numbers.
    • Order of operations is critical, following the PEMDAS rule: Parentheses first, then Exponents, followed by Multiplication and Division from left to right, and Addition and Subtraction last.

    Algebra

    • Variables represent unknown values, while constants are fixed values.
    • Expressions combine variables and constants without an equality sign, while equations include an equality sign.
    • Solving equations involves isolating the variable using inverse operations to maintain balance.
    • Functions define a relationship between inputs and outputs, ensuring each input has one output.

    Geometry

    • Basic geometric shapes include triangles, squares, circles, and various polygons.
    • Properties such as perimeter, area, and volume are essential for measuring shapes.
    • The Pythagorean theorem relates the sides of a right triangle, while angle properties include complementary and supplementary angles.
    • Coordinate geometry utilizes points, lines, and slopes within a Cartesian plane for graphing shapes and functions.

    Trigonometry

    • Key trigonometric ratios are sine, cosine, and tangent, relating angle measures to side lengths in right triangles.
    • The unit circle is a vital tool for understanding trigonometric functions across different angles.
    • Applications include calculating angles of elevation and depression and examining periodic functions, which model cyclical behaviors.

    Calculus

    • Limits are fundamental for analyzing function behavior as they approach a specific point.
    • Derivatives measure the rate of change and the slope of a tangent line to a curve.
    • Integrals calculate the area under a curve and represent the accumulation of quantities.
    • The fundamental theorem of calculus establishes a connection between differentiation and integration.
