Multiply Divide, Add Subtract

In any equation you have to

First: Multiply and/or Divide then

Last: Add and/or Subtract

Will not go to the rules of parenthesis in depth anymore. I assume you know the Hierarchy {[( )]}

Now for the positive and negative symbols. (+ and -)

Multiplying and Dividing

+ * + = +

+ * - = -

- * - = +

Adding and Subtracting

These are the rules of basic arithmetic, so you should not have any problems here.
