Choosing Operations

Choosing operations is the mathematical process of deciding whether addition, subtraction, multiplication, division, or a combination of operations best represents a problem. This decision depends on the relationships among quantities, the information provided, and the question being asked; words, units, diagrams, and known operation properties can help identify whether values should be combined, compared, repeated, or partitioned. Developing this skill strengthens problem-solving because students must translate real-world situations into mathematical expressions, select an efficient strategy, and check whether the result is reasonable. It supports work with arithmetic, fractions, measurement, algebraic expressions, and quantitative reasoning across science and everyday decision-making.

In capital budgeting, selecting positive NPV projects adds value to a company. Although businesses ideally pursue all positive NPV projects, managers often face budget constraints that limit the amount of capital they can invest within a given period. In such cases, the goal is to maximize the total NPV while staying within budget limits. For example, a chocolate manufacturing company has a $100,000 budget and two projects under consideration. Project A requires an investment of $80,000, with...
