Put the inputs in the boxes and choose the operation. Use PI and NE 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 *p*
if you want to use data that you have written or copied in the **M** or **p** box; **p** is also used as "Pr" of the binomial distribution;
you can also add or multiply **data** by** p**.
Use **Round** to round to units or digits after or before them.
