hp49g+ bug? Combinations, sums, and equivalence  Eddie Shore  03152005 The following is true: i.e. if n = 5
COMB(5, 2) + 5 = 5! รท (3!*2!) + 5 = 10 + 5 = 15
However, when I input Both objects inputed are same type (9  algebriac expressions?).
A bug in the 49g+ CAS perhaps.

Re: What's RTFM? :)  bill platt  03162005 Which is actually taken as a friendly reminder or suggesttion among friends. It only shows irritation when you get to, "RTFM41" which means, "read the "funny" manual for once!" Another version is RTFD41 for which "D" stands for "drawing" as in mechanical drawing. regards, Bill
