Concepts of pre algebra
Introduction :
Basic math pre-algebra is a general name for a course in middle school mathematics. In the United States, it is normally taught between the seventh and ninth grades, although it may be necessary to take this course as early as sixth grade in order to advance to Calculus BC by twelfth grade. The purpose of pre-algebra is to prepare the student for the study of algebra.

In this article we shall discuss about the some concepts of pre algebra
Addition & Subtraction
This part will help you better understand, work with and solve equations when they include addition and/or subtraction in them.

Pre algebra concepts with examples and explanations:
Here we will learn some concepts of pre algebra
Associative property: Three or more numbers are involved in associative property. Its nothing but a grouping of numbers.
Equation: 1
x + (y + z) = (x + y) + z
Any number plus 0 (zero) equals itself.
Equation: 2
x + 0 = x
Identity Property: If the value is added to the number the value remains unchanged.
Equation: 3
X = y
x + z = y +Z
x - z = y - z
When answering equations remember to addition and subtraction are inverse operations they undo each other (i.e. 10 + 9 - 9 = 10). To answer equations by addition and subtracting, first decide which operation has be applied, then use the inverse operation to undo this (remember to add or subtract from both sides of the equation).

Some examples problem for learn basic math pre algebra concepts
1. The example for pre algebra to find x value x + 76 = 148
Solution:
x + 76 = 148
Subtract 76 on both sides, we get
x + 76 - 76 = 148 - 76
x = 72
Hence the answer is x = 72
2. Solve: x - 54 = 156
Solution:
x - 54 = 156
Add 34 on both sides,
x- 54+54 = 156+54
x = 210
These are basic math pre algebra example problem
