Question about Casio HR-100TMPlus Calculator

Open Question

We bought a casio hr-100tm for basic calculations but can't get it to perform simple adding and subtracting without the minus sign appearing when it shouldn't and other esoteric calculations which we do not need. How do I get it back to basic calculations like adding, subtracting and dividing?

SOURCE: my calculator will not let me add or subtract percentages.

It would appear most Casio’s have a similar problem I believe this could be a fault in their programming and am awaiting reply from Casio and some of its distribution outlets.

SOURCE: how to reset tax % on casio HR-100tm

Hi,

Press the CA button twice. Then push and hold down the %/set key until the 0 disappeared and reappears. Then type in your tax rate and the percent key (Eg: 8.25%) and then press the TAX+ key. It should save the new tax rate.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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.

Couldn't find a manual or user guide. The closest I got were two pages, one with the calculator, and one with the group of calculators that explains some of the functions.

Answer always appearing


Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

Hi there, i have the same problem with the Casio fx 83ES. Simple Sums difficult without Exp?


The Enter Exponent key may be marked as x10^x. It is in the last row of keys, near the =/EXE. To enter a negative exponent use the change sign key (-), not the minus key for subtractions.

How do I get this calculator to substract


Big calculators work a little different than handheld calculators. Like the above commentor explained, if you have a basic "whats 100 minus 20?" You have to entered as 100 + 20 -- And when you hit the minus button at the end, it will give you the total. 100 is the positive number, and the 20 is the negative number that your subtracting. Also you can hit 20 -- 100 + and get the same total because you entering 20 as the negative and 100 as the positive, just in reverse.

My calculator will not let me add or subtract percentages.


I have a Casino MS-80S and yea, the percentage works different. As example to take 100 and subtract 10%, this is what I do: 100 X 10% - and then I get the answer 90 after I press the minus key. To add the percentage instead, 100 X 10% + will give me an answer of 110, after I press the plus key.
