Elementary Algebra

"Elementary," as the name suggests, the "fundamentals of algebra." Beginners start with basic algebra. If a person has no knowledge of arithmetic (arithmetic, the division that includes addition, subtraction, multiplication and) must start with elementary algebra.
In algebra, we use variables instead of numbers. Variables aid in the generalization of the concept of problem solving, so if we have different values, but a similar situation, then simplyChange the value of the variable helps.

There are many laws that years of study and the conclusion was that the algebra is derived quite simply perform the calculation. The basic rule is that the polynomial of highest degree are located on the left, and decreases the level as you move from left to right. The constants (numbers) are on the right hand side (RHS) of the "=" and all the variables on the left side (LHS). A system is "solvable" if there is at least as manyThe equations (or statements) as the number of unknown variables.

The art of algebra, one has the properties of real numbers to study in detail (associative, distributive, etc.).

Examples of linear equations: 3x + 100 = 250

Examples of quadratic equations: (x +1) (x +2) = 12

Examples of systems of linear equations: 3x + y = 25, x - 2y = 5

Besides all the positive points in algebra, is another that defines it as "unsolvable problems." If the equation does nothave a possible solution, then the system of equations is unsolvable.
Nor a system of equations, or infinitely many different solutions. These systems are classified as "undeterministic"

Systems with more number of variables and fewer equations are considered "undetermined." These systems also in the category of undeterministic because no solution can be determined, but since it was due to lack of information is brought to anotherClass of equations.

Similarly, the system of equations with more equations than the number of variables called "overdetermined" is. In this category we have to repeat the information. Normally, there are factors of the same equations repeatedly.

Now, the realization of the examples will give you more experience in this field. Remember: "There are no shortcuts in mathematics, only practice."

Starting from the basics of algebra and then go to the more complex features would be betterIf you are a student and the fear of mathematics. Finally, we all aim to reduce our problems, right?

Happy problem solving!
