First, to understand the basics of Algebra you should be familiar with the following operations:
Generally most people prepare by taking Pre-Algebra which covers all the basics necessary to begin Algebra.
Most people begin by learning some terms that are common in Algebra. Those are:
Now Algebraic Expressions are composed of, Terms.
45x² ÷ 16y² - √51, with 45x², 16y², √51, all being terms. Even the number 1 is a term.
A term can have, a coefficient, a constant, and a variable. A coefficient is the first number in a term. A constant is a single number with no variable attached. An a variable is a letter, as it can "vary" - hence the term variable.
As mentioned above Algebraic Expressions do not have equal signs, that's because If any set of algebraic expressions contain an equal sign, this defines an Equation.
You may be asked to solve an Algebraic Sequence.
The above example calls for finding the missing number. If you're good in the basics of math you'd eventually see the pattern is +15 to each number.
You will also learn that there are different types of Numbers. There are:
You will need the understand that Algebra does not operate exactly as Arithmetic. In arithmetic you add, subtract, multiply, and divide straight across. In Algebra things have be done in an order. This is called the Order of Operations.
You must follow the order of:
When you're dealing with equations they're generally broken into:
A monomial is an equation or expression consisting of one term.
A binomial is an equation or expression consisting of two terms.
A trinomial is an equation or expression consisting of three terms.
And lastly, a Polynomial is an equation or expression consisting of four or more terms.

Pre-algebra is essentially the basics of algebra. Algebra can be tough for many, so as a way to break the ice, you (ussually) take a pre-algebra course before algebra itself. Algebra is a very large subject, spanning multiple years of courses in most (if not all) schools. After pre-algebra, you have to work with many algebraic equations in the later courses, which cannot be understood without learning the basics that are taught in pre-algebra.
Since "pre-" means before, then pre-algebra would be before algebra. Conversely, algebra would be after pre-algebra. Generally, the next class after a pre-algebra class would be Algebra I, followed by Algebra II.
Pre-algebra preps you for algebra.2nd answer:Pre-AP-algebra is the same as Algebra I. Both are way harder than pre- algebra.
