There are a number of important interactions in Mathematica between evaluation and pattern matching. The first observation is that pattern matching is usually done on ...

The fundamental operation that Mathematica performs is evaluation. Whenever you enter an expression, Mathematica evaluates the expression, then returns the result. Evaluation ...

Mathematica's scheduled tasks provide a way to set evaluation of arbitrary expressions in the future. Tasks can be scheduled for one-time evaluation, or for repeated ...

Interrupt Evaluation interrupts the current operation being performed by the kernel.

Refine[expr, assum] gives the form of expr that would be obtained if symbols in it were replaced by explicit numerical expressions satisfying the assumptions assum. ...

Parallelize[expr] evaluates expr using automatic parallelization.

When you see a two-dimensional expression on the screen, you can edit it much as you would edit text. You can for example place your cursor somewhere and start typing. Or you ...

ParallelSubmit[expr] submits expr for evaluation on the next available parallel kernel and returns an EvaluationObject expression representing the submitted ...

The functions FindMinimum, FindMaximum, and FindRoot have the HoldAll attribute and so have special semantics for evaluation of their arguments. First, the variables are ...

"FindEvaluatingCell" is a front end token that finds the currently evaluating cell.
