In calculus, infinite sums and products can pose a challenge to manipulate by hand. Mathematica can evaluate a huge number of different types of sums and products with ease.

Numerical sums and products. This gives a numerical approximation to ∑_(i=1)^∞((1)/(i^3+i!)). There is no exact result for this sum, so Mathematica leaves it in a symbolic ...

In many computations you are concerned only with the final result of evaluating the expression given as input. But sometimes you also want to collect expressions that were ...

Parallel Kernel Status opens a dialog with statistics on active parallel kernels.

$Pre is a global variable whose value, if set, is applied to every input expression.

CellEpilog is an option for Cell which gives an expression to evaluate after each ordinary evaluation of the contents of the cell.

Toggle Breakpoint toggles a breakpoint on or off.

TraceOriginal is an option for Trace and related functions which specifies whether to test the form of each expression before its head and arguments are evaluated.

Step Out stops the debugger after finishing all evaluations in a stack.

TraceOff is an option for Trace and related functions which specifies forms inside which tracing should be switched off.
