Simplify Expressions

[gmontalv]

I need rules to simplify expressions:


3 -5/2 * 3 3/2
----------------
3 7/2 * 3 -9/2

How do I work this? It says to write answers with positive exponents only.

Did you learn BOMDAS at all?

This helps you with the order to simply equations - broadly speaking do the multiplication and division before addition or subtraction.

3 -5/2 * 3 3/2
----------------
3 7/2 * 3 -9/2


= 3 -(5/2 * 3 3/2 )
----------------
(3 7/2 * 3) -9/2

using brackets helps to see what parts to focus on first.

now have a go.
