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.
