## Algebra

Algebra is a branch of mathematics that deals with symbolic computation and the manipulation of symbols, usually representing numbers, using certain rules. At its core, algebra involves finding relationships between quantities and solving equations to find the values of unknown variables. This branch of mathematics was developed more than two thousand years ago by the ancient Greeks and has since evolved into various branches such as linear algebra, abstract algebra, and universal algebra, among others. Algebra is essential for understanding many mathematical concepts and applications across different fields, from calculus to geometry and beyond.

## Subtopics within Algebra

### Linear Equations and Inequalities

Linear equations are equations that relate variables with degree one or order one. They have many real-world applications, including modeling situations where an input leads to an output that is directly proportional to the input. In addition, linear equalities are also used in business problems like finding the cost per unit of goods produced. Linear inequalities are similar but include greater than or less than signs rather than equals. These inequalities can model constraints like a budget limit or available resources.

Quadratic equations involve terms with degree two (the highest power of x or another variable). Solving these equations involves techniques like completing the square and factoring. Quadratic functions, which are related to quadratic equations, describe relationships between inputs and outputs where the output is proportional to the square of the input. These functions have a parabolic shape and are used in many areas of mathematics and physics.

### Systems of Equations

Systems of equations involve multiple equations with multiple variables. These systems can be solved to find the values of the variables simultaneously. The solutions are determined based on whether the system has a unique solution, infinite solutions, or no solutions.

### Polynomials

A polynomial is a sum of powers of a variable, possibly with constant terms. They are used extensively in mathematics and have applications in areas like computer graphics and cryptography. Polynomials can be added, subtracted, and multiplied according to specific rules, and they are essential in algebraic equations and systems of equations.

### Functions

Functions are relationships between inputs and outputs where each input is associated with exactly one output. They can be represented using various notations like f(x), y = mx + b, or g(x). Functions have numerous applications across different fields, including modeling physical phenomena, calculating probabilities, and developing algorithms for computer science problems.

Algebra also includes more advanced topics such as inequalities, matrices, determinants, eigenvalues, and transformations, which are typically covered in higher level mathematics courses (e.g., Algebra II or college-level mathematics courses).
