The following table lists the functions that are valid in equations. Appendix G, 
"Operation Index" also gives this information.

For convenience, prefix–type functions, which require one or two arguments, display 
a left parenthesis when you enter them.

The prefix functions that require two arguments are %CHG, XROOT, IDIV, RMDR, 
nCr and nPr. Separate the two arguments with a comma.

In an equation, the XROOT function takes its arguments in the opposite order from 

RPN usage. For example, –8



3 



 to is equivalent to .

All other two argument functions take their arguments in the Y, X order used for 

RPN. For example, 28



 4 



 

x

 is equivalent to .

For two argument functions, be careful if the second argument is negative. These are 
valid equations:
