To change the task number you must press and hold % (rate set) for 3 to 5 seconds, should appear tax XX %, now type your tax number and press % again and AC. To test type "100" press TAX + and the result should be 110, if your tax rate is 10% for example.

'CASIO' appears on screen (Casio MS-80S calculator) - what does this signify?


This is just a wild guess, you understand, but could it possibly be the name of the manufacturer ?

How do I use the % button on the casio MS-80b calculator- when I try to do a deduction or any calculation with the % button it gives the wrong answer


It seems you have to use the key procedure exactly to get the correct result.

From the Casio website,

Make sure that you are following the correct procedure.
Adding 10%: 200 [×] 10 [%] [+]
Subtract 10%: 200 [×] 10 [%] [-]

Good luck,

Paul

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 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.
