Quote:On any HP calculator, a Solver function (so limited to that tool) that solves all markup, cost, price, margin (MU CST PRC MAR) problems, finding all possible solution variables by solving for any possible solution variable.This is a user interface problem, not a problem with making a programming language do the required mathematics using additional keys and keystrokes. The main point of the thread is that HP firmware engineers could have made the MU CST PRC MAR keys on the HP 10bII+ (and other calculators) work as users expect instead of giving errors for valid input-output cases. Specifically, once the 4 variables involved are cleared to zero, these 12 keystroke sequences must work (plus entering the inputs in any order). Code: # Keystrokes Solves For 4/9/21 error correction: "02 20 MAR 4 CST MU -> MU, PRC" (corrected) was "02 25 MU MAR -> MAR" (error, duplicate of row 05). |
