Put the inputs in the boxes and choose the operation. Use PI [or 3.141592653589793] and NE [or 2.718281828459045 or exp(1)] instead of *π* and *e* [Euler's number].
Use *A* or *B* or *C* if you want to use previous output as input. Use *M* and *Q*
if you want to use data that you have written or copied in the **M** or **Q** box; **Q** is also used as "Pr" of the binomial distribution;
you can also add or multiply **data** by** Q**.
Use **Round** to round to units or digits after or before them.
