Question about Calculators

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.

I had the same problem, so I read another casio manual, as I couldn't find one for this model and found this solution. Do the calculation like this 66 x 50 % + or 66 x 100 % +

As for changing the tax rate + - buttons, I have no idea.

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.
