The order in which we evaluate expressions can be ambiguous. So, what are we to do? Of course, grouping symbols would remove the ambiguity.
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.

1-2 Order of Operations and Evaluating Expressions
The order in which we evaluate expressions can be ambiguous. If we do the addition first, then. Parentheses, brackets, or curly braces can be used to group parts of an expression. Each of the following are equivalent:. Note how the expression contained in the parentheses was evaluated first. Another way to avoid ambiguities in evaluating expressions is to establish an order in which operations should be performed. The following guidelines should always be strictly enforced when evaluating expressions.
The student will evaluate whole number numerical expressions, using the order of operations limited to parentheses, addition, subtraction, multiplication, and.

With student input, put the operations in order. For example, the expression 7 x 2 is equal to Also learn to identify coefficients and frame algebraic expressions and phrases. Plug in three different values of the variable.
In mathematics and computer programming , the order of operations or operator precedence is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression. For example, in mathematics and most computer languages, multiplication is granted a higher precedence than addition, and it has been this way since the introduction of modern algebraic notation. With the introduction of exponents in the 16th and 17th centuries, they were given precedence over both addition and multiplication, and could be placed only as a superscript to the right of their base. These conventions exist to eliminate notational ambiguity, while allowing notation to be as brief as possible. Where it is desired to override the precedence conventions, or even simply to emphasize them, parentheses can be used to indicate an alternative order of operations or to simply reinforce the default order of operations.
