    Key Concepts in Mathematics

    Basic Arithmetic

    • Addition (+): Combining two or more numbers to get a sum.
    • Subtraction (−): Finding the difference between numbers.
    • Multiplication (×): Repeated addition of a number.
    • Division (÷): Splitting a number into equal parts.

    Algebra

    • Variables: Symbols representing unknown values (e.g., x, y).
    • Expressions: Combinations of numbers and variables (e.g., 3x + 2).
    • Equations: Mathematical statements of equality (e.g., 2x + 3 = 7).
    • Functions: Relations that assign exactly one output for each input (e.g., f(x) = x^2).

    Geometry

    • Shapes:
      • 2D: Circles, triangles, rectangles, polygons.
      • 3D: Cubes, spheres, cylinders, pyramids.
    • Properties:
      • Perimeter: Total distance around a shape.
      • Area: Space contained within a shape.
      • Volume: Space contained within a 3D shape.

    Trigonometry

    • Triangles: Relationships between angles and sides.
    • Functions: Sine (sin), cosine (cos), tangent (tan).
    • Pythagorean Theorem: a² + b² = c² for right triangles.

    Calculus

    • Differentiation: Calculating the rate of change (derivatives).

    Patterns and Sequences

    • Arithmetic Sequence: A sequence with a constant difference between terms.
    • Geometric Sequence: A sequence with a constant ratio between terms.
