Describe the order of operations and explain how it is used to simplify expressions. Explain specifically the order in which mathematical operations must be performed to correctly simplify an expression. Provide an example of a real-life situation in your current or future profession where a specific order of steps is necessary for a proper end result. What will happen if the proper order is not followed? (Humor and creativity are encouraged, if used appropriately.) Develop an original mathematical expression which must be simplified using order of operations. Include addition, subtraction, multiplication, division, exponents, and at least one set of parentheses. Simplify the expression INCORRECTLY, showing each step as you simplify. DO NOT include the reasons for each step. Do not include variables (letters) in your expression.
