What is what does it mean to evaluate in math?

In mathematics, to "evaluate" means to find the value of something, typically a mathematical expression. This often involves substituting numbers for variables and performing the indicated operations, following the order of operations (https://www.wikiwhat.page/kavramlar/Order%20of%20Operations - PEMDAS/BODMAS).

Evaluation can apply to different mathematical entities, such as:

• Expressions: Evaluating an algebraic expression (https://www.wikiwhat.page/kavramlar/Algebraic%20Expression) means simplifying it to a single numerical value if possible.
• Functions: Evaluating a function (https://www.wikiwhat.page/kavramlar/Function%20(Mathematics)) involves plugging in a specific value (or values) for the input variable(s) and calculating the corresponding output.
• Limits: Evaluating a limit (https://www.wikiwhat.page/kavramlar/Limit%20(Mathematics)) means determining the value that a function or sequence "approaches" as the input approaches some value.
• Integrals: Evaluating an integral (https://www.wikiwhat.page/kavramlar/Integral) (definite integral) usually means finding the numerical value of the area under a curve between two specified limits.

Essentially, evaluation is the process of finding the "answer" or the "result" of a mathematical problem or statement.
