How to use this calculator
Edit the index, limits and factor. Multiplying k from 1 through 5 gives 120.
Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know
Large products can exceed time or display limits. Infinite products require separate convergence analysis.
Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
