![]() If you elect to go to RPN you should be aware of the need to manage the stack unless you limit yourself to the simplest kind of arithmetic. In this forum you will always get a recommendation to use RPN as a more natural way of doing arithmetic. Message #7 Posted by Martin Pinckney on, 1:52 p.m., The "fancy ideas" quote is from page 120 of Wlodek Mier-Jedrzejowicz's A Guide to HP Handheld Calculators and Computers. Otherwise, you will eventually encounter stack overflow which will result in incorrect answers for apparently innocuous calculations. If you are comfortable with order of operation and the use of parentheses in evaluating equations you will not have a problem with calculators which use those methodologies and which are widely available from TI and Casio and in a few models from H-P. RPN is actually a lower order language akin to what I knew as machine language in computers. I have never found that to be so, probably because I had become proficient in higher order languages such as BASIC and FORTRAN in computers before obtaining my first electronic calculator. You can buy calculators which don't implement order of operation from H-P, TI and Casio but you will have a hard time finding them which offer the generally accepted scientific functions such as the trigonometrics and hyperbolics. Others suggest that business users have trouble with order of operation or ". Some say it is because the operation mimics that of the old mechanical desktop calculators. The reason that the business community accepts that methodology has never been clear to me. The 10b uses the the type of algebra that is generally accepted as appropriate for business calculators. It can not be considered a scientific calculator since the trigonometric functions are not available. The 10B is a capable business calculator. MANY eB** sellers refer to this model (and the 12c or 17b, etc.) as "scientific", but that is just ignorance, IMO. #HP 10B FINANCIAL CALCULATORS MANUAL#When you say "listed as a business/scientific calculator", do you mean by HP? My 10b manual only refers to it as a "business calculator". I own the HP 10B calculator which is listed as a business/scientific calculator. Message #5 Posted by Martin Pinckney on, 1:53 p.m., You may want to consider an HP 20b or the much faster 30b instead. RPN is a much more natural way to evaluate an expression and you never have to worry about the order of operations. The "order of operations" problem is one of the great reasons to use one of HP's calculators that supports RPN entry instead. Message #4 Posted by David Hayden on, 1:14 p.m., It's a pity, but I don't find them right now anymore d -) Many comments from technical/scientific people. There were also quite nasty remarks about the reasons for Chain mode in business/financial calculators (instead of ALG supporting the common mathematical operator precedence). IIRC, some extended discussions about RPN, ALG and Chain mode took place in this very forum in the past. Message #3 Posted by Walter B on, 12:44 p.m., The 10b and the later 10bII only implement chain algebraic, which evaluates as things are entered as you've noticed. Message #2 Posted by Tim Wessman on, 11:01 a.m., Re: Does the HP 10B calculator not support Order of Operation? entering 1+2x3 result in 9, when it should be 7).ĭoes this calculator not support this at all or does it have to be configured first? I noticed when entering simple algebraic equations, the calculator does not implement the order of operation feature which dictates multiplication/division operations are done prior to addition/subtraction.
