Links for other calculators posted here; links for other sources of information about calculators, including some possible sources for manuals.
Form for submitting information about your calculator , If you just want to ask me a question, you can use the "Contact information" link below. Contact information Site home page. If you stored something in a memory bank as shown on the display in the top left corner , perform the calculation up to the point of needing the stored value, then press the RCL key followed by the numeric key corresponding to which data bank the value is in.
Clearing memory banks completely involves using this article's process, instead right from your calculator. Add the displayed value to the running total of information inside a memory bank with the "SUM" key.
For example, one of your memory banks contains the number 35, yet you want to keep tally and add the displayed value 25 from the display to the memory. Just use this feature tap 2nd key-RCL and your memory will change to 60 so that memory will then change to be a value of 60 instead. If it's not displayed, you will need to enter it onto the display. Exchange data for memory values with the "EXC" key. Get the computation performed for the value you'd like to switch with a memory bank, then when you'd like to switch them, use the 2nd function EXC by pressing the STO key and typing the number for the memory bank which your value is found in.
If you'd like to switch it back, perform no other calculations and just repeat. Worry less about calculations involving a series of "order of operations" expressions with the parenthesis keys. The " " can be found directly above the 8 key, and " " can be found directly above the 9 key.
This process is fine to represent an expression where something needs to be done first, that wasn't given quickly to you. The User's Guide mentions the order of which items it takes into its order of operations. Single variable functions as written in the Owner's Manual include squares, roots, trigonometric functions, factorials, logarithmic functions, percents, reciprocal, and angle conversions.
Utilize keys allowing you to evaluate exponent expressions. Here you have a few choices. Use the quick x 2 key directly above the " " key to square the number.
Use the x 3 key to cube a number. This is a 2nd function of the 1 key. Utilize the "10 x " with care - knowing there are better forms out there for entering numbers of this type. The 10 x function is a 2nd key function of the "LOG" key on the top middle row key three over from the left.
Keep in mind the EE function controls the setting of scientific notated calculations, which is something this article will deal with later. There's always the "y x " key which can be used by inputting the "y" term with the power the item is raised by "x" as the next value entered, following a press of the "y x " key.
The "y x " key can be found directly between the "Off" and "division" keys. To input 9 to the 4th power, type 9 "y x " 4 then press the equals key. Utilize root keys if necessary. Solve a square root expression.
Solve a cubed root expression. This is a 2nd function key of the 0 key. This is a 2nd function key of the "y x " key. Input these as the "y" value first. To find the fourth route of , input then the 2nd key, then 4, and press equals the answer is 8. Find the decimal form for the inverse of the inputted value using the calculator. Enter a percent into the calculator. Percents are entered as if you are reading them. Press the percent key at the right time - this key can be found as the 2nd function of the 2 keys.
Calculate the percent of a number by typing the number you wish to determine multiplied by the full percent then press the percent key.
When the calculator determines you're entering a percent, it'll automatically calculate and convert it to the right decimal form from which it needs to enter the computation from. Calculate the ratio of one number to the other. Calculate add-ons and discounts using the percent key. Suppose you want to add a percentage tip to a digital order, cab ride, offline restaurant bill, or something similar where adding a percentage is necessary, using your calculator.
To find out how much you should tip the person along with the base amount, type in the amount, plus the plus sign, then the percentage number then put in the percent sign, and after that tap equals. Suppose there's a percent sale on clothing you'd like to see as the final price.
Enter the original price followed by a subtraction sign followed by the percent numbers, then the percent sign followed by the equals sign. That number is your item's on sale price. Change the display read-out at any time, if necessary to read a fixed decimal number of places answer.
If you don't care to read way too many numbers and want the value shortened a bit, use the FIX function - a 2nd function of the decimal key. Either before or during the calculation, set your device to read the number using the proper number of locations - rounding or adding additional numbers if necessary. Obtain the fixed value setting. Get your calculation done, then enter a fixed value. Get the function up, then tap the number of units inside the decimal you'd like to be displayed for instance, if you'd like to read a 4-digit decimal number with only three digits long after the decimal, call up the function then tap the number 3.
Clearing fixed notation involves calling the function then tapping the decimal point key meaning 2nd key, decimal, then decimal again. Keep in mind that your calculator takes no account in the rounding up of sales based on tax rates, so fixed notation should be set to one more than the minimal amount of numbers so you can do the right math and round it accordingly.
Set it to three to minimize the extraneous numbers and you do some of the math, based on what you find when its last digit - thousandths - reads anything other than 0. Part 2. Scientific 1. Find the reciprocal of the displayed or entered number. This button can be found underneath the "sin" button, just to the right of the "pi" button. The value you get is the approximation based on 1 divided by the value that was originally displayed on the screen.
You don't need to press the equals sign to get it to convert at any time. Learn about the EE key. This key is the way to enter values in scientific notation, though the screen will look confusing at first. Enter your decimal-formed mantissa then press the EE key, omit the x 10 - information the screen will have two pieces: your mantissa and just the exponent portion.
The exponent already takes into account the "x 10" portion, and if necessary, you can turn that negative, after entering the exponent value. Keep in mind that this calculator can only hold two digits of the exponent.
If the value has more, it can't hold any more digits to the expression. Utilize constants in calculations.
Locate and use the "pi" key. Your calculator calculates expressions with values up to 12 digits 3. Use the constant "K" to find out the effects of "K" on the progression of data. Enter the number based on the calculation - variable times or added to the constant K then press the equals button. Keep changing the variable then press equals each time. The letter K will appear in the top right corner of the calculator's display, as the constant is set.
If you decide to turn off your calculator, it will not permanently store this value for the next time you turn it on and it will remove itself from temporary memory. Constant K's don't work well when figured with subtraction and division and most other formats. However, it works well with addition and multiplication. With subtraction and division, it tends to hang answers from prior calculations on the display as answers to the expression.
Use Euler's constant. This function is traditionally used in the modeling of population growth and the depreciation of asset value. Plug the x-valued exponent in, and press the 2nd function for e x - located under the LN key.
Calculate logarithms. Calculate common logs. If you need to work in base 10, know the exponent, and need to calculate the argument the number you'd probably be looking up with a logarithm table in the olden days , your LOG button will be your friend. You don't need to enter the base because the calculator already understands it's to the base of 10, but you will have to enter the argument which is the number to the direct right of the log on your sheet to get your exponent.
To get the inverse - based on the argument to get the exponent - use the 10 x function described earlier in this article. Calculate natural logs. If you like to make things tough and like to work in base of the special constant, e as stated earlier - the LN key is your friend.
Enter the value to the left of the ln and press the LN key to find the exponent to the natural log. The inverse of a natural log was discussed earlier as the "e x " function and should be consulted from there. Type one value then call up the 2nd function using the pi key, then type another and call up the function again and the display will read the first function you inputted. Enter sines, cosines, and tangents.
If you know your angle measure sometimes called theta measurements , you can find the values for sines, cosines, and tangents by using your calculator.
Enter the angle value and find the answer.
