Math Example--Numerical Expressions--Order of Operations--Example 08	Math Example--Numerical Expressions--Order of Operations--Example 08 Watch the following video on Order of Operations. (The transcript is included.) Video Transcript A numerical expression includes numbers and operation symbols, addition, subtraction, multiplication, and division. Because addition is commutative, adding from left to right, or right to left, gives you the same result. The expressions 2 + 3 and 3 + 2 give the same result. But this isn't the case with all operations.	Numerical Expressions
