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. To deselect or reset the calculator to as many decimal places as the data supplies or results in:Ģnd-shift (yellow) FIX (in yellow). (The FIX key has the primary name CE/C, in white it is near upper right corner of the keypad.) To set the number of decimal places in the display:Ģnd-shift (yellow) FIX (in yellow), followed by the number of decimal places you want to set. SCI (3rd-shift 6) sets the display to scientific notation.įLO (3rd-shift 5) sets the display to fixed decimal notation. (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.
TI-36x 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) TI-36x 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.
TI-36x 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. Texas Instruments TI-36x scientific calculatorīottom of page return links and contact information
