Algebra 1 is a foundational math course that introduces students to the basic concepts of algebra. This includes topics such as arithmetic operations, algebraic expressions, linear equations, inequalities, and polynomials. Algebra 1 is typically taught in the ninth or tenth grade.

Algebra 1 examples are important because they help students to understand and apply the concepts they are learning in class. By working through examples, students can see how algebra is used to solve real-world problems. Algebra 1 examples can also be used to assess student understanding and identify areas where students need additional support.

This guide is organized by topic, with each section providing a variety of algebra 1 examples. You can use this guide to review specific topics, or you can work through the examples in order. If you are unsure of how to solve an example, be sure to consult your textbook or teacher for assistance.


Arithmetic operations

The four basic arithmetic operations are addition, subtraction, multiplication, and division. Algebra 1 examples involving arithmetic operations can be as simple as evaluating an expression such as $2 + 3 – 1 \times 4$ or as complex as solving a multi-step equation.

Algebraic expressions

An algebraic expression is a combination of numbers, variables, and mathematical operations. Algebra 1 examples involving algebraic expressions can include simplifying expressions, expanding products, and factoring polynomials.

Linear equations

A linear equation is an equation that can be expressed in the form $ax + b = y$, where $a$ and $b$ are constants and $x$ and $y$ are variables. Algebra 1 examples involving linear equations can include solving equations for one variable, graphing linear equations, and writing linear equations to represent real-world situations.


An inequality is a mathematical statement that compares two expressions. Algebra 1 examples involving inequalities can include solving inequalities for one variable, graphing inequalities, and writing inequalities to represent real-world situations.

Systems of equations

A system of equations is a set of two or more equations that share the same variables. Algebra 1 examples involving systems of equations can include solving systems using elimination, graphing systems, and using systems to solve real-world problems.


A polynomial is an algebraic expression that consists of variables and coefficients, added or multiplied together. Algebra 1 examples involving polynomials can include simplifying polynomials, factoring polynomials, and using polynomials to solve equations and inequalities.

Quadratic equations

A quadratic equation is an equation of the form $ax^2 + bx + c = 0$, where $a$, $b$, and $c$ are constants. Algebra 1 examples involving quadratic equations can include solving quadratic equations using the quadratic formula, graphing quadratic equations, and using quadratic equations to solve real-world problems.

Radical equations

A radical equation is an equation that contains a radical expression. Algebra 1 examples involving radical equations can include solving radical equations for one variable, graphing radical equations, and using radical equations to solve real-world problems.

Rational expressions

A rational expression is an algebraic expression that consists of a polynomial divided by another polynomial. Algebra 1 examples involving rational expressions can include simplifying rational expressions, multiplying and dividing rational expressions, and solving rational equations.

Exponents and logarithms

An exponent is a mathematical symbol that indicates how many times a number is multiplied by itself. A logarithm is the inverse of an exponent. Algebra 1 examples involving exponents and logarithms can include evaluating exponential and logarithmic expressions, solving exponential and logarithmic equations, and using exponents and logarithms to solve real-world problems.


A function is a relationship between two sets of numbers, such that each input produces a unique output. Algebra 1 examples involving functions can include graphing functions, writing function equations, and using functions to solve real-world problems.


Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles. Algebra 1 examples involving trigonometry can include solving trigonometric equations, graphing trigonometric functions, and using trigonometry to solve real-world problems.


This guide has provided a comprehensive overview of algebra 1 examples, from basic arithmetic operations to advanced trigonometry concepts. If you are struggling with a particular algebra 1 topic, be sure to review the examples in this guide and consult with your teacher or textbook for additional assistance.

Q.What are some real-world applications of algebra 1?

Algebra 1 is used in a variety of real-world applications, including:


A business owner is trying to determine how many products she needs to sell in order to make a profit. She knows that her costs are $10 per product and that she sells each product for $15. She can use the following linear equation to determine the number of products she needs to sell:

15x - 10x = 1000

Solving for x, we get:

5x = 1000
x = 200

Therefore, the business owner needs to sell 200 products in order to make a profit.
