Yes, that is "correct". "Correct" in quotes because "percent" really just means "one-hundredths", so 10% is exactly equal to 0.1.
Other calculators might decide to interpret it differently, but the operation 18.9 - 10% = 18.8 is still a technically correct answer. You might want to try 18.9 * 90% instead.

I hadn't noticed until I read your post and tested it, an you're right, it sucks!
But I have the solution, look for mobilecalculator.exe in the \windows folder. Create a shortcut to it in your \windows\Start Menu folder and you're set!
This is the original version that works like normal people expect a calculator to work

Many thanks for that pat12

Well. I'll be blowed, didn't know it done that!!! Only had the phone a few days
The % was incorrect also; 100-20%=99.8??? How strange
In portrait mode the calculator operates as a business calculator, but in landscape mode it works as a scientific calculator.
To demonstrate this enter the following exactly as written into your calculator in both modes:
3 + 2 * 5
In portrait mode it will give 25 as the result, whereas in scientific mode it will give 13 as the result. Both are correct in context. In scientific mode it will use operand precedence - hence the multiplication will be carried out before the addition if it's not used with parenthesis.
For the OP's original question, the correct result will be obtained if you divide the original sum by the (percentage plus 1) you wish to deduct. e.g for 10% use 1.1 for 17.5% use 1.175 ... and so on.
So to deduct 10% (say as a discount) from 18.90 then type in 18.90 divided by 1.1 to give the result 17.181818r
Conversely to add on a markup multiply the net amount by the percentage value plus one.
Simples!

Wait...
...am I hearing you correctly?
You're saying the ability of a calculator to do math properly "sucks"?
Are you kidding...REALLY?!
haha just need a calculator which can use the feature we buy from store that kind of calculator.
i dont really own a scientific calculator but i think even a scientific calculator also work this same way
xx - 10% = u get ur ans.

u need to turn ur mobile to landscape u will see more feature
I can not even see a "%" on my calculator??? Is it a hidden option?
Cheers
There is another calculator bild in windows. Try TC and find calc.ink in windows folder and copy to "start menu/programs". This prog calculating properly in this way
mate, now I know maths isn't the greatest subject in the states... but all of you?
ok, j/k
2% = the second part out of one hundrer = 0.02... hope this is clear
so if you press 2% and then equals, you'll get 0.02, which is correct
if you try, 100-20%, you will get 99.8, which is correct again. if you want to get 0.8, then you have to use the brackets (100-20)%

and i case you didn't know it yet, what % does is to devide the number to 100... obviously
and since, in the equation 100-20% (which really is 100-20/100), the division has a greater priority, that's the operation that comes first...
