Evaluating at
To evaluate the polynomial when , one must substitute for every occurrence of to obtain . Following the order of operations, the exponent is evaluated first, producing . Next, the multiplication steps yield . Adding the terms sequentially results in , which mathematically simplifies to a final value of . This step-by-step example demonstrates the proper application of substitution and the order of operations in evaluating an algebraic expression.

When a financial analyst is asked to 'evaluate' a revenue expression for a specific number of sales, which two steps must they perform according to the mathematical definition of evaluation?
In a professional setting, formulas are often used to calculate key performance indicators (KPIs) and other business metrics. Match each mathematical term to the specific action it describes within the process of finding the value of a formula.
A logistics coordinator is using the expression 15w + 10 to calculate the shipping fee for a package, where 'w' is the weight in pounds. To 'evaluate' this expression for a 5-pound package, arrange the steps of the process in the correct order according to the mathematical definition of evaluation.
The Two Steps of Evaluating an Expression
In a professional business application, the process of 'evaluating' an algebraic expression is considered complete once a specific number has been substituted for the variable, regardless of whether the resulting numerical expression has been simplified.
In a logistics department, a coordinator uses the expression 15w + 10 to calculate shipping costs, where 'w' is the weight of a package. When the coordinator replaces the variable 'w' with the number 5 to find the cost of a specific shipment, they are performing the first step of evaluation, which is known as ________.
