My original one began to have issues a couple of years ago, so I purchased a new model of the HP calculator (42 and 33S) both great calculator, but it was nothing like my original 32SII As an engineer I rely on my calculator on a day to day basis. I purchased this HP 32SII calculator because I originally owned one when they first came out in 1989. (Links for other calculators posted here links for other sources of information about calculators, including some possible sources for manuals.)įorm for submitting information about your calculator, (If you just want to ask me a question, you can use the "Contact information" link below.Great calculator, but unfortunately they do not mfg. Main page for "Using your scientific calculator". If yes, how would you like your name listed? ("handles" ok.) May we list your name in the collection (at the web site), to give you credit for providing this information? We will not make your e-mail available in any case. We will not list your name at the web site without your explicit permission. Please provide your name and e-mail, so I can check back with you if there are questions (and maybe have you proofread the web page for your calculator). Not commonly used.)īoth of these functions work on a pair of values, in the X and Y registers. The grad is 0.9 degree, so that a right angle is 100 grad.
(Some calculators also have an option for "grad". These are functions we do not use in intro chem, but which you are likely to use in other math and science courses. How are the keys labeled for natural logs and antilogs? We do not use these in intro chem, but you are likely to use them if you go much beyond that. That holds for other one-key functions, such as antilog and square root: enter the number first, then the function.īase e logs (log e or ln) are called natural logs. That is, enter 1000 LOG (= left-shift LN). To take the log 10 of 1000 which do you enter first, the number or the LOG key? * On some calculators, you press the LOG key before the number, and on some you press the number then the LOG key. For example, the log 10 of 1000 is 3 and then the antilog 10 of 3 is 1000. The log 10 is the power of 10 of the number. In intro chem we most often use base 10 logs (log 10), for example with pH. Not important for most people.)įor scientific notation: Left shift, DISP, LN, then number of decimal places to display.įor fixed notation: Left shift, DISP, square root key, then number of decimal places to display.
(Some calculators also have an option for "Engineering notation", which is a variation of Scientific notation. Many calculators allow you to set the number of decimal places displayed. HP-32SII Most scientific calculators allow you to "force" the display to use (or to not use) scientific notation. What is the key for making an exponent negative? When entering a number that starts with 1x in scientific notation, do you need to enter the 1? (e.g., 1x10 12) HP-32SII What is the label on the key for entering exponents? * The key for making an exponent negative is the same key used for entering negative numbers. Do you need to enter the 1 to get the correct answer, 2x10 12? Do it twice, once with the first 1 and once without it. * A special case concerns entering a number that starts with 1x in scientific notation: do you need to enter the 1? Try it. Identify the key used to enter the exponent. "right shift": bent arrow pointing to the right (blue key) "left shift": bent arrow pointing to the left (orange key)
HP-32SII What is the label on the "shift" key(s) Shift keys are used to get the second (or third) function for a particular key. Otherwise, you will figure that out later on the form. If you know which type yours is, you can write that here. On an RPN calculator, you type "2 ENTER 3 +".Īlgebraic calculators can be further subdivided into AOS and DAL.
To add two numbers (say, 2 & 3) on an algebraic calculator, you type the keys "2 + 3 =". Does your calculator use algebraic or RPN (reverse Polish notation) logic? How do you tell? An algebraic calculator has an = key An RPN calculator has an ENTER key. Bottom of page return links and contact information
