What Is Algebra?
Algebra is a branch of mathematics that uses letters and other symbols to represent numbers.Dictionary Definition
The Oxford English Dictionary defines algebra as "the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations."
Equations ("Tetris" Game)
Here is an interactive game to help you learn about equations.
- Each falling equation has a correct answer and a wrong one.
- Click on the correct one to score points and to make the equation disappear.
- If you click on the wrong one (or do not click), the equation will fall to the bottom.
- The wrongly answered or unanswered equations will start to build up.
- When the screen is full, you're toast.
- Good luck!
Where Does the Word "Algebra" Come From?
Algebra comes from the Arabic word al-jebr, which means "reunion of broken parts".Albert Einstein and Algebra
The famous scientist Albert Einstein learned algebra from a young age.
His Uncle Jakob gave him books on the subject and called algebra "a merry science".
He compared algebra to hunting a little animal. You didn't know the name of the animal, so you called it "x". When you finally caught the animal you gave it the correct name.
The Curriculum
The lessons are grouped into mini-curriculum to help you organise your learning. A brief description is given for each mini-curriculum. Click the MORE button to learn more.Algebra Definitions
There are many different words used in algebra, such as equation, variable, coefficient, term. Understanding algebra is easier when you understand what each of these words mean. In this mini-curriculum, you will learn all the definitions.

Equation
An equation has an equals sign (=) and tells us two values are equal. Here is an example of an equation:
Constant
A constant have a fixed value. In the equation below, the 2, 1, and 9 are constants.
Variable
A variable is a symbol that stands for a number. Its value is not fixed - it can take any value. In the equation below, the x is a variable.
Coefficient
A coefficient is a number that is placed in front of a letter. The coefficient is multiplying the variable. In the equation below, the 2 is a coefficient.
Exponent
An exponent tells you how many times a number (or symbol) is multiplied by itself. It is written to the right and above the number. In the equation below, the 2 is an exponent.
Operator
An operator defines an operation, such as +, −, ×, and ÷. In the equation below, the + is an operator.
Term
A term is a collection of one or more numbers, letters and brackets written next to each other (they are multiplied together). Terms are separated by + or − operators. In the equation below, the 2x2, 1 and 9 are terms.
Expression
An expression is one term or several terms that are added (+) or subtracted (−) together. In the equation below, the 2x + 1 and 9 are expressions. They are separated by the = sign.

Arithmetic with Letters
Algebra uses letters and other symbols to represent numbers. Just like numbers, the letters and symbols can be added, subtracted, multiplied and divided. In this mini-curriculum, you will learn arithmetic with letters.
more...
Adding Letters
Adding letters works when the letter is added to numbers, other letters and the same letter.
Subtracting Letters
Subtracting letters works when the letter is subtracted by numbers, other letters and the same letter.
Multiplying Letters
Multiplying letters works when the letter is multiplied by numbers, other letters and the same letter.
Dividing Letters
Dividing letters works when the letter is divided by numbers, other letters and the same letter.

Adding Terms
Terms can be added.
Subtracting Terms
Terms can be subtracted.
Multiplying Terms
Terms can be multiplied. The coefficients are multiplied, and each letter must appear in the result as many times as they appear in the multiplication.

Laws of Exponents in Algebra
An exponent tells you how many times a number, letter or term is multiplied by itself. In this mini-curriculum, you will learn how to use the law of exponents in algebra.
more...
Laws of Exponents
The laws of exponents in algebra let us understand how a letter can be multiplied by itself.
Exponent of −1
A letter with an exponent of −1 is equal to 1 divided by the letter.
Multiplying Powers
When the same letters with different exponents are multiplied together, the exponents can be added.
Dividing Powers
When the same letters with different exponents are divided, the exponents can be subtracted.
Powers of Powers
A power of a power is where a letter with an exponent is itself raised to an exponent. When a letter with an exponent is raised to another exponent, the exponents can be multiplied.
Powers of Products
A power of a product is where a term containing letters multiplied together is raised to an exponent. Each letter in the term is raised to the exponent.
Negative Exponent
A letter with a negative exponent is equal to 1 divided by the letter with the exponent made positive.

Like Terms
Like terms are terms which have the same combination of letters, each with the same exponent. The only difference allowed between terms that are like terms are the numbers and signs in front of them. In this mini-curriculum, you will learn how to find like terms and how to collect like terms to simplify expressions.
more...
Like Terms
Like terms have the same letters with the same exponents. x, 2x and −x are like terms, they all contain x; only the number or sign in front of them is different. a2b, 5a2b and 1⁄2a2b are like terms, they all contain a2b; only the number or sign in front of them is different.
Identifying Like Terms
Identify like terms in an expression by finding terms with the same letters and exponents.
Adding Like Terms
Like terms can be added. Add the coefficients together.
Subtracting Like Terms
Like terms can be subtracted. Subtract the coefficients from each other.
Collecting Like Terms
Collect like terms by adding and subtracting the like terms you have identified. This simplifies the expression.

Expanding Brackets
Expanding brackets means multiplying terms inside of a pair of brackets in order to remove the brackets from an expression. In this mini-curriculum, you will learn how to expand brackets.
more...
Expanding Brackets
Expanding a single pair of brackets means multiplying the term outside of the brackets with each term inside the brackets. This removes the brackets.
Expanding Brackets with the Grid Method
Brackets can be expanded using the grid method. This is a useful method if you prefer using pictures to understand a method.
Expanding Double Brackets
Expanding double brackets means multiplying the term in two pairs of brackets that are written next to each other. This removes the brackets.
The FOIL Method
FOIL stands for Firsts, Outsides, Insides, Lasts. It helps you remember an order to multiply terms when expanding two pairs of brackets.
Multiplying Expressions
Multiplying expressions means writing each expression in a pair of brackets and expanding them.
Expanding Double Brackets with the Grid Method
Double brackets can be expanded using the grid method.

Solving Equations with Brackets
Some equations in algebra contain brackets. In this mini-curriculum, you will learn about how to solve equations with brackets.

Solve Equations with Brackets
To solve equations with brackets, expand the brackets and rearrange the equation to find what x equals.
Solve Equations with Two Sets of Brackets
To solve equations with two sets of brackets, expand both brackets and rearrange the equation to find what x equals.

Factoring
Factoring is the opposite of expanding brackets. It is a way of simplifying an expression. In this mini-curriculum, you will learn about factors in algebra, the greatest common factor and how to factor expressions.
more...
Factors
A factor is one of the numbers, letters and brackets (or a product of them) that are multiplied together to make a term.
Finding Factors
You can find factors of terms by looking at the numbers, letters and brackets (with any exponents) that appear in the term. The factors of 2x are 1, 2, x and 2x.
Greatest Common Factor
The greatest common factor is the largest factor that is common to two or more terms. The greatest common factor of 2xy and 2xz is 2x.
Finding the Greatest Common Factor
Find the greatest common factor by looking at the numbers, letters and brackets that appear in two or more terms.
Factoring Expressions
Factoring simplifies an expression by writing it as a product of factors. It lets you write an expression where terms are added together to one where they are multiplied together to make a single term.
