On 10-key calculators you can press the x key twice to turn on the constant feature. How do you do that on this calculator

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.

Turns out to be the = key. I just double-checked it and it's true.

Do a calculation like 10 divided by 2. Every time you enter a number and then hit the equal key, it will be divided by 2.

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.

I'm sorry, but I have no idea what you're trying to do. If you're following instructions given on some web page, then I suggest you refer any questions to the author of that page.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and hold the diamond key. Press and hold the + key for a few seconds and see whether the screen becomes legible.

If this doesn't do it, please reply to this post and we'll go on from there.

If your calculator has the capabilities to do constant calculations here is how you perform calculations with a constant.

- Enter the constant (4)
- Press the operation key (/) once.
- Press the operation key (/) a second time.
- Your calculator may show a k in its display (LCD)
- To divide a number by 4, enter the number and press =
- To divide another number by the constant (4) , Enter the number and press =
- Keep entering the dividends and pressing =

Press AC twice. Hold down % set key for about 2 seconds until ?0? disappears on screen, then reappears. Press Tax Rate key. Input tax rate (12.5%) and press % set key.

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.

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 multiplie**r 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
