What Are the Basics of Algebra? 

Algebra is one of the first math subjects that most students learn. It can be intimidating at first, but with a little patience and understanding, algebra is actually one of the most straightforward topics in mathematics. Here are some basic algebra basics you should know:

The Definition of Algebra and the Different Types

The first thing that you need to understand is that algebra is a set of mathematical concepts that deal with operations, relationships, and expressions. This includes addition, subtraction, multiplication, and division. 

It also involves linear equations and quadratic equations. In elementary algebra, there are simple variables such as x, y, and z that are represented in the form of equations. These are called linear equations, quadratic equations, and polynomials depending on their degree. 

These expressions can be used to find solutions for problems, such as calculating the number of hot dogs left when you only eat half of your lunch. This is why algebra is often used in everyday life and in the workforce. 

What Are Variables?

The main objective of algebra is to determine the value of a variable in an equation. This can be done by figuring out what the variable is, finding a solution to the problem, or determining which side of the equals sign contains the value of the variable. 

In most equations, the variable is the one that has to be isolated on one side of the equals sign in order to find out its value. For example, if you have the problem 2x + 3 = 11, then you need to isolate the variable x on the left side of the equals sign so that it is clearly visible. 

This isolation process is known as transposition and is typically performed with the aid of an app like Photomath, which will scan the problem and bring up a step-by-step explanation. You can also search for the exact problem in your Photomath app to find a detailed, expert-verified solution. 

Solving Algebraic Equations

The most common type of equation you’ll encounter in algebra is a linear equation, which consists of numbers and/or variables on both sides. This makes it easy to figure out what the variable is by putting it on one side and then dividing the number of times the value of the variable has to be divided by the answer to getting a single number on the other side. 

For most algebra equations, you’ll need to use the commutative and associative rules to find the value of your variable. These rules will help you find the correct value for your variable in a single equation, which can be tricky. 

You’ll also need to understand the properties of algebra, which can be confusing at first but are really useful when it comes to navigating algebraic equations. These properties make it easier for you to understand what is going on, which helps you solve your problems quickly and accurately.
