Formula Manipulation and Simplification

Simplify or modify expressions, substitute parts of expressions

Most mathematical expressions can be represented in different, but mathematically equivalent forms. Some of these forms might look simpler; for example, they can be visibly shorter. However, there is no universal idea as to which form of an expression is simplest. The form of a mathematical expression that is simplest for one problem turns out to be complicated or even unsuitable for another problem.

If the problem you want to solve requires a particular form of an expression (expanded, factored, or expressed in particular terms), choose the appropriate simplification function. If you do not need a particular form of an expression, use simplify to shorten it.

You also can substitute for any part of an expression with a new value by using subs.
