Arithmetic

• Arithmetic is the foundation of mathematics, focusing on basic number operations.
• Addition involves combining two or more numbers.
• Subtraction involves finding the difference between two numbers.
• Multiplication is repeated addition.
• Division is the inverse of multiplication, finding how many times one number goes into another.
• Properties of numbers, like commutative, associative, and distributive, significantly simplify calculations.

Algebra

• Variables, typically represented by letters, are used to represent unknown values.
• Equations represent relationships between variables and numbers.
• Solving equations involves isolating the variable to determine its value.
• Inequalities show relative order relationships, such as greater than or less than.
• Polynomials are expressions consisting of variables and coefficients.
• Linear equations represent straight lines on a graph.
• Quadratic equations represent curves, often parabolas.

Geometry

• Geometry studies shapes and their properties.
• Basic shapes include points, lines, angles, triangles, and circles.
• Concepts like area and perimeter help quantify space and shapes.
• Volume is a measure of the space inside a three-dimensional object.
• Transformations, including rotations, reflections, and translations, describe movements of shapes.
• Spatial reasoning is critical to understanding geometric concepts.

Calculus

• Calculus deals with continuous change, allowing a deeper understanding of functions and their behavior.
• Differentiation helps find rates of change, or slopes of tangents.
• Integration is the reverse of differentiation and helps find areas under curves.
• Derivatives are essential for modeling physical phenomena, such as velocity and acceleration.
• Fundamental Theorem of Calculus connects differentiation and integration.
• Limits are a crucial concept in calculus, defining the behavior of functions as values approach certain points.

Types of Numbers
