Exponents and Order of Operations

Topics for Today:

As with any language, algebra has some basic rules that must be followed to arrive at a correct answer.  Sometimes there are multiple ways to express an answer or number so we need a set of rules to follow so we always arrive at the same answer for any one particular problem.  The order of operations is a set of rules that tells problem solvers which operations to perform and in what order.
