## order of operations and evaluating expressions

The order in which we evaluate expressions can be ambiguous. So, what are we to do? Of course, grouping symbols would remove the ambiguity. Parentheses, brackets, and absolute value bars can be used to group parts of an expression. For example:. Thus, if the example above is grouped as follows, we are forced to evaluate the expression inside the parentheses first. Another way to avoid ambiguities in evaluating expressions is to establish an order in which operations should be performed.

It seems that each student interpreted the problem differently, resulting in two different answers. Student 1 performed the operation of addition first, then multiplication; whereas student 2 performed multiplication first, then addition. We need a set of rules in order to avoid this kind of confusion. Mathematicians have devised a standard order of operations for calculations involving more than one arithmetic operation. The above problem was solved correctly by Student 2 since she followed Rules 2 and 3. Let's look at some examples of solving arithmetic expressions using these rules.
