In study of Pre Algebra, we come across the following types of problems and then we follow certain rules and patters to solve the Set of Pre Algebra, problems. Prealgebra includes the study of solving the mathematical expressions and getting the solutions for the expressions with the real and integral values. While we study Pre Algebra, it includes the placement of variables and forming the expressions with the Combination of the variables, constants and the mathematical operators. It includes the study of the order of operation of expressions and getting solutions for it.

Here we will learn the hierarchy of operations to be performed for solving the exponents, getting the solution of the Algebraic Equations. We will learn the methods of forming the algebraic expressions with the help of the statements and similarly we also learn to evaluate the values of the unknown variables and thus getting the solution.
The methods of forming the equations can be learned at the initial stage so that the child is able to learn the concept of algebra at the initial stage and thus he is ready to perform larger operations of algebra in higher grade mathematics. The study of Pre Algebra helps to translate the verbal phrases in the form of the mathematical and the algebraic expressions. We will learn to define and form the algebraic sentences and to translate Open Sentences into algebraic equations. The child is able to learn the rules followed for understanding the Order of Operations, which helps us to get the result out of the algebraic expressions. In other words we say that the pre algebra is the basic study of algebraic expressions and the algebraic operators in order to get the solution to the equations so formed, which are basically formed by the simple verbal statements.

Topics Covered in Pre-algebra

Simple Roots and Power

posted on: 30 Jun, 2012 | updated on: 06 Sep, 2012

Roots and powers are related to each other. Square root of a number must be equals to power 2 of another number. Simple power can be defined as simple repetition of the number in the product form. This can be shown by the following example.
In expression ‘PQ’, term ‘P’ denotes a constant number and Q is power number P. If we take P = 3 and Q = 2 then expression w...Read More

Factorization

Factorization can be understood easily if you are familiar with word ‘factor’. When we multiply any two Numbers and get third as its answer then those two numbers are termed as factors of resultant number. In simple words, factorization is defined as decomposition of things or an object into several products of another thing. In Math, factorization means crumbling of a num...Read More

An equation is defined as expression or Mathematical Expression which involves equals to symbol in it. According to the rules of an equation, left hand side of equals to symbol must be equivalent to right hand side of equals to symbol. It can be represented in format x + y = 12. Here, x and y are variables, whose values can be changed and need to be determin...Read More

Quadratic Equations
