Create a square matrix at mots 3X3. Then you can multiply it by a scalar, or scare it, or calculate its determinant, and inverse. With two matrices that have the same dimensions you can perform .additions/subtractions or multiplications.
Short answer is no. These are low end calculaotors and parts are hard to obtain. These calculators are cheap and basically disposable. It is cost prohibitive to replace the printer in them.
Sorry.
I think Duff H gave you good advice. Can you include picture of the back of the calculator? The picture that Duff H posted shows the battery compartment door. There is no need to unscrew the back of the calculator, just put your thumb on straight lines and push towards the top of the calculator. It may take extra pressure if the batteries have leaked inside the case.Good luck.Paul
Good Morning Fhaas153
Looking at a J-10 picture on eBay
http://www.ebay.com/itm/VINTAGE-CASIO-J-10-ELECTRONIC-CALCULATOR-8-DIGIT-TESTED-/331587643662 , the picture of the rear says '1.5V battery x 2. Looking at this other shot
http://www.casio-calculator.com/Museum/Calculator/FGHIJ/J-10/Casio-J-10-back.jpg It looks like there is a fairly clear Slide-to-Open Battery door at the top of the rear panel. Given the battery rating at 1.5 Volts and the door size, I'd suspect it'll take either AA or AAA batteries. You should be able to slide the door and look, and most battery compartments will have an indication of the specific cell.
To be sure I'm covering both the what and the how, slide the door open. Remove old batteries if still there. Clean up contacts with a bit of fine steel wool if they are corroded or covered with old battery fuzz. Put new batteries in - negative end towards the coil springs generally. Replace sliding hatch.
Hoping this covers what you're looking for!

To use the log function, use the log key. To use the antilog function, use the antilog key by hitting shift first, and then the log key.
For example, if we are trying to solve for n in the equation A=P(1+i)^n, where we have A, P and i, and want ot solve for n, we take the logs of both sides and we get log A = n log (1+i). To get n by itself, we divide both sides by log (1+i), we get n = log A /(log (1+i).
Good luck,
Paul

The answer is correct. It is your understanding of priority of operations that is at fault.
As written your expression is calculated as follows
-2/2600 +10+3.
To ensure that an expression is calculated as you want it, enclose parts of it in parentheses. See the screen capture below.
I assume you want an exponent. On this calculator you use the ^ key.
For example, enter 3, enter ^, enter 3, = should give you 27.
Let me know if you have any questions.
Good luck.

I think this is a solar calculator. On many solar calculators, there isn't an off button. You just stop using it and after a set period of time (6 minutes for this calculator), it turns off by itself.
Good luck.
