How to do constant division on Casio dr-210tm calculator? I can do the multiplication, but not the division. When I try to do the division, I get zero for the result instead of the expected number. Th

Check Casio's website. You might be able to download one there.

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents
Division with the same base - subtract the exponents
Exponent to an exponent - multiply the exponents
Negative exponent - 1 over the same number to the positive exponent
Zero exponent - anything to the exponent 0 is 1

Good luck,

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).

Youll find your answer right here in the manual:

Just pull it out, take a pair of tweezers and pull, there is no easy way to do if you can't make it feed out.

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

This process actually requires fewer keystrokes than 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)

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

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