Introduction of basic math pre algebra:
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.

Addition & Subtraction
This part will help you better understand, work with and solve equations when they include addition and/or subtraction in them. Please express your views of this topic What is Dependent Variable by commenting on blog.
Explanation of basic math Pre algebra :
Important Things to Remember
Associative property: Three or more numbers are involved in associative property. Its nothing but a grouping of numbers.
Equation: 1
a + (b + c) = (a + b) + c
Any number plus 0 (zero) equals itself.
Equation: 2
a + 0 = a
Identity Property: If the value is added to the number the value remains unchanged.
Equation: 3
a = b
a + c = b + c
a - c = b - c
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).
I have recently faced lot of problem while learning Riemann Sum Calculator, But thank to online resources of math which helped me to learn myself easily on net.
Example and practice problems for basic math Pre algebra :
Some examples problem for learn basic math pre algebra concepts
1. The example for pre algebra to find x value x + 56 = 128
Solution:
x + 56 = 128 To variable through itself
(Isolate the variable).
x + 56 - 56 = 128 - 56 To undo adding 56, subtract
56 from both sides.
x = 72
2. Solve: x - 34 = 345
Solution:
x - 34 = 345You need to isolate the variable.
x - 34 + 34 = 345+ 34 To undo subtracting 34, add
34 to both sides.
x = 379
These are basic math pre algebra example problem
