## Algebra for Dummies

If you’re anything like me, the word “algebra” sends a shudder down your spine. It’s probably been a while since you’ve had to think about equations and variables, but trust me, it’s not as bad as you remember. With a little review (and maybe some extra help from a friend or tutor), you can get back up to speed in no time.

Here’s a quick overview of what algebra is all about: Algebra is the mathematics of equations and variables. In other words, it’s the math we use to solve problems that involve unknown values. For example, if I wanted to know how much money I would have after saving for 10 weeks, I could use an equation to figure it out.

This is where algebra comes in handy!
There are three main types of algebraic equations: linear, quadratic, and exponential. Linear equations are the simplest kind – they involve one variable and can be graphed on a straight line.

Quadratic equations are slightly more complicated; they involve one variable squared (like x2) and can be graphed on a curved line. Exponential equations are the most complex; they involve variables with exponents (like 2x) and can be graphed on a graph that looks like an upside-down U.
Don’t worry if this sounds confusing – it will all become clear with some practice.

The best way to learn algebra is by working through lots of examples. So grab a pencil and paper (or fire up your favorite computer program) and let’s get started!

## What is Algebra

Algebra is a branch of mathematics that deals with the study of symbols and the rules for manipulating those symbols. In algebra, we use letters to represent numbers. This allows us to state relationships between numbers in a way that is much more concise than writing out equations using only numbers.

For example, the equation x+3=5 can be written as a statement: “The variable x represents the number 2.”
Algebra is not just about solving equations though. It is also about finding patterns and generalizing those patterns.

Algebraic thinking can help us see relationships in data sets and make predictions about what might happen next. It is a powerful tool for solving real-world problems.
So what exactly is a variable?

A variable is a symbol that represents a value that can change. In the equation x+3=5, the variable x represents the unknown value 2. We can solve this equation by finding out what value of x will make the equation true.

In algebra, we often use letters to represent variables because they are easy to work with and understand. However, any symbol could be used to represent a variable; we could even use words like “cat” or “boat” if we wanted to. The important thing is that whatever symbol we choose should be consistent throughout our work so that we can keep track of what it stands for.

## What are the Basic Principles of Algebra

Algebra is a branch of mathematics that deals with the study of symbols and the rules for manipulating those symbols. In elementary algebra, these symbols (generally letters of the alphabet) represent numbers or unknown quantities that can be determined through solving equations. The goal of algebra is to find a general solution that can be used to solve a variety of problems.

There are three basic principles that underlie algebra:
1) The principle of equality states that equal things must be treated equally. This means that the same operations can be performed on both sides of an equation and the results will still be equal.

For example, if we add 5 to both sides of the equation x + 3 = 5, we get x + 3 + 5 = 5 + 5, which simplifies to x = 8.
2) The principle of substitution states that we can substitute one value for another in an equation as long as we do so consistently throughout the equation. So, if we know that x = 8 from above, we can substitute 8 for x in any other instance where it appears in our equation.

For example, if we have the equation y – x = 10, substituting 8 for x gives us y – 8 = 10, which simplifies to y = 18.
3) The principle of order states that equations must be solved in a certain order depending on what type of operations are being performed. Generally speaking, you solve equations starting with parentheses first, followed by exponents/roots, multiplication/division (working from left to right), addition/subtraction (again working from left to right).

This is sometimes referred to as the Order Of Operations. Following this order ensures that all equations are solved correctly.

## What are Some of the Applications of Algebra

Algebra is the branch of mathematics that deals with the study of the rules of operations and relations, and the constructions and concepts arising from them. Algebraic methods are used in many different fields, including physics, engineering, economics and biology.
In physics, algebra is used to describe the laws of nature.

In engineering, it is used to design and build structures and machines. In economics, algebra is used to model financial markets. In biology, it is used to understand the structure and function of living organisms.

## How Can I Use Algebra to Solve Mathematical Problems

Algebra is a powerful tool that can be used to solve mathematical problems. By studying algebra, we can learn how to solve equations and how to graph linear functions. Algebra can also be used to solve problems in geometry and physics.

In fact, algebra is a very versatile tool that can be used in many different ways.
One way to use algebra to solve mathematical problems is by using equations. An equation is a statement that two things are equal.

For example, the equation x+3=5 says that x+3 is equal to 5. We can use this equation to solve for x, which means finding out what x equals. To do this, we simply rearrange the equation so that all of the terms with x are on one side of the equal sign and all of the other terms are on the other side.

This gives us: x+3-3=5-3 or x=2. So we have found that x equals 2!
Another way to use algebra is by graphing linear functions.

A linear function is a function whose graph is a line. For example, the function y=2x+1 produces a graph that looks like this:
To graph a linear function, we first need to find its intercepts (the points where it crosses the axes).

The intercepts of our example function are (0,1) and (2,-3). Next, we plot these points and draw a line through them. This gives us our graph:

As you can see from the graph above, when graphing linear functions we can use slope and intercepts to help us determine certain features about the function such as its domain and range (the set of values it outputs for given inputs). Additionally, once we have graphed a linear function we can use it to answer questions about specific points on its curve (for example, what is the y-coordinate of the point where x=4?).
