Important things to remember Grouping Symbols – anything grouped… including information above or below a fraction bar and parenthesis. Exponents – anything in the same family as a ‘power’… this includes radicals (square roots). Multiplication- this includes distributive property (discussed in detail later).

Some items are grouped!!! Multiplication and Division are GROUPED from left to right (like reading a book- do whichever comes first Addition and Subtraction are also grouped from left to right, do whichever comes first in the problem.

So really it looks like this….. Parentheses / Grouping Symbols Exponents Multiplication and Division (left to right) Addition and Subtraction (left to right)

Example #1

Example #2
