How to do constant multiplication or division on the Canon P170-DH calculator

This process actually requires fewer keystrokes than most other calculators. Basically, just do the first problem
and then do the next items with just the next number and the EQUAL key. For example,

*** Constant Multiplication ***
2 (multiply key)
10 (= key)
(The answer 20 shows on the screen. Note, the 2 is still stored as a constant without doing anything, just continue)
4 = (shows the answer 8 on the screen)
20 = (shows the answer 40 on the screen)
100 = (shows the answer 200 on the screen)

*** Constant Division ***
10 (divided by key)
2 =
(shows the answer 5 on the screen, the 2 is still stored as a constant without doing anything, just continue)
100 = (shows the answer 50 on the screen)
500 = (shows the answer 250 on the screen)
4 = (shows the answer 2 on the screen)

--------------
Also note! There is no K visible on the screen to indicate a constant is set.

How do I set a constant for division?


On some calculators there is a key marked with K (on the key or around it on the calculator face).
Try entering the divisor then the division key then press K. If that does not work try another order.
On some other calculators you press the operation key twice. Try entering the divisor first then press the division key twice. The next number you enter will be divided by the one enter before pressing the operation key. (divisor).

Try pressing an operation key twice.
For example to multiply any entry by 15, you would enter 15, press the multiplication key twice. Now to calculate the products of you list of entries by 15, you just enter number in your then press =. c.then the second number and =, etc.

How to Use a TI-30XA
The TI-30XA is a scientific calculator with many functions. You can calculate problems with fractions and decimals, as well as solve problems of probability and functions. A scientific calculator computes the number sentence you type in using the order of operations: parentheses first, then roots and exponents, then division and multiplication and, finally, addition and subtraction.

Instructions
  1. How to Use a TI-30XA
    • 1

      Press the [ON/C] key to turn on the calculator. Press the [OFF] key to turn it off. To use the calculator in solar mode, put the solar panel in the light and then press the [ON/C] key. To turn it off when in solar mode, slide the calculator cover back on and it will automatically shut off.

    • 2

      Replace the batteries by first removing the cover and placing it face down. Use a Phillips-head screwdriver to unscrew the back panel. Remove the back panel and change the batteries. Screw the back panel back on. Press [OFF] [ON/C] and [ON/C].

  • Use the basic operation keys for addition [+], subtraction [-], multiplication [x] and division [/]. To change the signs of your values from positive to negative or vice versa, press the [+ -] key before the numbers you enter. Use the parentheses, [(] and [)], to command the calculator to solve what is inside the parentheses first. Press the [=] to solve the number sentence you entered into the calculator.

  • 4

    Find percents of a number by first typing in the number, then [x], then the percent number, [2nd], [%] and, finally, [=]. The [2nd] key allows you to use the commands that are written above each key. For example, to find 20% of 100, type in 100 [x] 20 [2nd] [%] [=] and the display will show the answer, 20.

  • 5

    Turn decimals into fractions by entering the decimal value, then pressing the [2nd] and [F D] keys, then [=]. Turn the fraction back into a decimal by pressing [2nd] and [F D] again. For example, to turn 0.5 into a fraction, type in 0.5 [2nd] [F D] [=].

  • 6

    Turn mixed numbers into improper fractions by entering the mixed number first. Type in the whole number, then the [a b/c] key, then the numerator, the [a b/c] key again and the denominator. Next, press [2nd] [d/c] [=], and the calculator will convert your mixed number into an improper fraction. Press [2nd] [d/c] again to turn it back into a mixed number. For example, to turn 1 1/2 into an improper fraction type in 1 [a b/c] 1 [a b/c] 2 [2nd] [d/c] [=], and the display will show the answer 3/2.

  • 7

    Switch the notation setting of the calculator between engineering, scientific and floating. To select scientific notation, press the [2nd] and [SCI] keys; this will display your answers in scientific notation as a number between 1 and 10 to a power of 10. Press [2nd] [ENG] to switch to the engineering setting; this setting displays values as a number with an exponent that is a multiple of 3. Press [2nd] [FLO] to switch to the floating setting. This is considered standard notation and will display the answer as a standard number.

  • 8

    Use the left arrow key to go back and delete numbers to the right of the cursor that you typed into the display. This must be done before you press [=]. To clear the screen, values and operations, press [ON/C] and [ON/C] again in battery mode, or [CE/C] and [CE/C] again in solar mode.


  • Hope it helps your problem. Thanks!

    Does a HR-100TM have a constant operation mode


    You have to enter your constant factor and then hit the multiplication key twice and you will see a 'K' pop up on the left side of the screen. Then you can enter your other number, hit = and another number, hit =, etc..
    3.96**8=31.68
    16=63.36

    Is there a constant function in casio fx83es


    I do not think that this function is implemented on this calculator. But that should not be a problem. You can use the replay function to display the command line for editing. When the previous command line is displayed use the cursor key to change the second multiplicand (for multiplication).
    That may not what you want, but I was just trying to show you a workaround. Feel free to use it.

    How to use the log function for acidity constants? I get a syntax error


    Hi,
    Let Ka be the acidity constant (acid dissociation constant). The pKa is defined as the negative of the log in base 10 of the acidity constant.
    pKa= - log_10(Ka) where log_10 is the logarithm in base 10.

    To calculate the pKa you use the key labeled [LOG], just above [COS]. Be careful with the negative sign: For that, you use the key [(-)] just above the RCL key. Press the keys in the order specified below

    pKa = [(-)] [LOG] number [ ) ] [=]

    Although the right parenthesis is not required in this particular case, it is better to accustom oneself to close the parenthesis.

    Hope it helps.

    NOt exactly a problem as my Casio SL-1100TV calculator works fine. What I am trying to find out more about is the 'K' function, when you can press the + button twice and it carries over the number that...


    Hello,

    If you have say to multiply 100 numbers by one single multiplier ( you have 100 multiplications to perfom) you use the Constant function abbreviated to K.

    This is how you go about it
    in a*b , a is called multilpicand, b is the multiplier.
    You enter the multiplier (6) then you press twice on the multiplication key. You are ready to repeated the some operation but with a different multiplicand
    You enter the first mutiplicand then you press = (or enter) the result is displayed.
    Every number you are going to enter will be multiplied by 6
    [6][*][*] -------constant multiplication with 6 as multiplier, Then
    [5][=/ENTER/EXE] yields 30
    [6][=] yields 36
    [0.5][=] yields 3.

    Be careful!! If you do not enter a new multiplier and just press [=] the calculator uses the last calculated result as the multiplicand. (On certain calculators, the last result is stored in a register called Ans (short for answer.)

    What I described for the multiplication is valid for any arithmetic operation. Thus
    [6][+][+] is constant addition with 6
    [18][/][/] is constant division with 18 as divisor.

    Hope it helps
