I would have expected this to be easy to find. But, no Ubuntu calculator applications seem to have binomial coefficient function built in.

I know I can just do the formula each time with factorial. But, it would be nice just to have it built into the calculator.

  • Open GNOME "Calculator".
  • Enter the following as input: nCr(n;r)=n!÷r!÷(n−r)! (I recommend to copy and paste the code I provided.)
  • You have now defined a new function with name nCr.
  • You can use it like any predefined "Calculator" function. For example enter: nCr(4;2) to get the output of 6.

Note that functions that are defined by a user are stored in a user configuration file and can be reused in future gnome-calculator invocations. The location for custom function definitions is:

~/.local/share/gnome-calculator/custom-functions

Speedcrunch has the ncr function. Simply type ncr(10,4).
