Oh, so I have to convert the percentage to a decimal? I say the results are inconsistant because with some problems I get the correct result, mainly with subtracting percentages, but when adding to them, like for sales taxes, it's usually wrong.
I'm asking this mainly because I'm working with a deaf-blind person who has to take a test on using a calculator, in which there are percentage problems dealing with money, and it will be rather embarrassing to explain that the "smart braille display" cannot handle percentages which an old talking calculator can do with ease. Very disappointing.

What do you mean “doesn’t produce consistent results?”
How are you entering the problems? For 10% of 40, you’d do 40*.1 which equals 4.

Thanks,
Bill

Hi all. Tried to send this yesterday but I suppose it didn't work. So, I'm 
trying to enter percentage problems in math with the VU calculator, problems 
like 10 percent of 40, with 40+10%100. This does not produce the correct result 
all the time, with all problems I try. So, how can I do this consistantly, 
percentages I mean?
