Printing problem with casio HR-100TM calculator

Make sure you have the right AC adapter plugged in. I have two Casio printing calculators of different sizes with two different adapters. Though the input plug fits either calculator, only one of them is meant for the HR-100TM

What does the MU/MD key on the Casio HR-100TM do?

Here's how to use the MU/MD key. Say you want your item that COSTS you $120 to be priced such that you end up with a 40% margin. MU'MD calculates the final price to achieve the margin. Enter: 120 X Enter: 40 MU'MD Result: 200.00 Proof: 200 - 120 = 80 / 200 = 40% Essentially the same as using the COST/ SELL/ MAR keys. The Casio HR-100Tm manual is pretty pathetic. Expected a better one on their website, but alas.

Casio seem to have a problem with the percentage key

The issue is the fact that you are adding the %. You need to Multiply it by 1.1 instead of trying to add 10%. This is a wonky equation anyway, because your not specifying what you want to add 10% of. This is why you are getting a weird answer.

My calculator fx-991 Es is showing either syntax

How about recreating the error and reporting faithfully the error message? You get a syntax error if you try to invert a matrix by using the wrong key sequence such a
[SHIFT][MATRIX][3:MatA][X to ] -1), meaning that you use the universal power key on the same row as X squared and log and between them.
To calculate the inverse of a matrix, have the name of the matrix on the command line, (see above) then press [X to -1] key one row up from [log].

Concerning your implied affirmation that if the matrix is square you should not be getting any error: You will get an error ( a Math error) if determinant of the matrix is equal to zero.

How to calculate mode with caso fx-991ES

MOD simply calculates the remainder that is left over after dividing by the MOD parameter.For example, 10MOD7 = 3 since you can only divide 7 into 10 once, leaving a remainder of 3.For larger numbers, eg 389487MOD31 you start by dividing 389487 by 31, which gives 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD calculation has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculators working capacity.An alternative method is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.
