To reduce a mathematical expression to its simplest form is to:

• A. Simplify
• B. Factor
• C. Expand
• D. Evaluate

Answer: (A)

Reducing an expression to its simplest form means rewriting it so that no further simplification is possible. This typically involves combining like terms and reducing fractions or radicals as much as possible. For example, combining 2x and 3x gives 5x, and simplifying 6/9 yields 2/3. The goal is to end up with an expression where terms are as simple as they can be and no further reductions are available. Other actions rearrange or change the structure of an expression but don’t necessarily produce the simplest form. Factoring rewrites an expression as a product of factors, expanding uses distributive property to remove parentheses, and evaluating substitutes numbers for variables to obtain a numerical value. These are useful tools, but they don’t always result in the expression’s simplest form.
