Each key except a few had a secondary function instruction above the key it uses, and the power key had a colorful border. As of the current model, most of that has changed. This article may at times refer to using the 2nd function.
The User Guide was never good to explain where each 2nd function was - instead referring to the process as 2nd then in square brackets mentioning the function itself - leaving the reader stranded, hunting for that particular key never once explaining which key the function is controlled by.
This article will try to explain these as "functions of the 2nd key" or "2nd function of the x key" - and where they are found on the calculator.
For simpler functions, they will be explained in the order they need to be inputted, mentioning where to find each key. Learn where a solar version once differed from the battery-operated calculator if you still have one available. These differences are still notated in the user's manuals of battery-operated calculators bought new from stores starting in Recognize the basic functions that you'll need to know to solve basic arithmetic.
A common skill necessary for this device is finding certain areas of the calculator that you'll need to know, including the numeric keypad and arithmetic operators. The numeric keypad can be found towards the bottom four center rows in columns 2 through 4 not taken into account by the operators. Learn the location of your arithmetic operators. On your right-hand column, you'll see five keys ordered from division to multiplication, subtraction to addition, to the equals sign in the very bottom right corner.
The arithmetic keys are a little lengthier from top to bottom and take a more squarish appearance as opposed to the rectangular appearance of most of the other keys. Enter a negative value so the calculator can interpret it. Learn your clearing buttons. Over in the bottom left corner, you'll find the key to backspace one number from the right of the entry you've created.
It's written as a left-ray arrow. Learn about entering fractions. Two keys on this keypad are used to enter fractions. Enter fractions by typing your numerator into the top, then pressing the key, then typing your denominator. However, it will display on your calculator as "2 underscore 1 arc off the bottom line 3". Turn a mixed number into an improper fraction. Using the 2nd key in the top, type your mixed number, then press the 2nd key followed by the fraction key.
Turn a fraction into a decimal formatted number. Type your fraction using the fraction format, then tap the 2nd key, then press the backspace key at the very bottom left corner the one used to remove a digit. Turn a decimal into a fraction. Type your decimal in the decimal form then tap the 2nd key and tap the same backspace key. Turn this decimal into its own fraction with its component decimal bars.
Learn about storing and recalling values, and how this calculator utilizes these features. Much like memory banks on calculators, these keys allow you to grab values stored in memory to be used in another calculation. Storing the value requires not only locating or entering the value to be stored, but it also requires entering which memory bank should be used to store the value.
However, once values are stored in each of the three banks, if you try to enter another value in a memory bank except for the value "0" , it'll overwrite its stored data.
Entering the value requires typing the value then pressing the STO key next to the 7 key then typing either 1 for memory 1 , 2 for memory 2 , or 3 for memory 3. Recalling the value requires not only entering the calculation up to the point of the need to plug in your value, but also adding the value into the calculation. 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.
