Simplifying Expressions

The aim of this lecture is to present on Simplifying Expressions of mathematics. Expressions: A group of symbols used to represent a number. Value: The number represented by the expression. There is no standard procedure for simplifying all algebraic expressions because there are so many different kinds of expressions, but they can be grouped into three types: those that can be simplified immediately without any preparation; those that require preparation before being simplified and those that cannot be simplified at all.
