Evaluate works for arguments of any symbol with attributes HoldAll, HoldFirst, or HoldRest: Since Attributes is HoldAll, use Evaluate to find the properties of the value of x: Unprotect a system symbol to make a definition for it: Force evaluation of the right-hand side of a delayed definition: Evaluate does not work inside functions with attribute HoldAllComplete: Use Unevaluated to temporarily treat a function as if it were HoldAll: Evaluate does not work inside Unevaluated: Evaluate works only on the first level, directly inside a held function: Unevaluated Activate ReleaseHold Hold HoldComplete HoldAll HoldAllComplete, Enable JavaScript to interact with content and submit forms on Wolfram websites. Evaluation Definition: Was ist "Evaluation"?

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations.
