    In short

    Is there any calculator in wp store that can key in 200x10%x30 and return 600?

    ...
    ...
    I want to be able to calculate percentage in windows phone using the % button and be able to calculate something else

    10 percent of 200 is 20, correct?

    Calculator in others eco system if you press
    200x10%=
    it would show
    20

    Calculator in Windows and Windows Phone (Calculator, Calculator Toolbox, Calculator2) If you press
    200x10%=
    it will show
    4000

    to make these wp app show 20 you will have to omit '=' and only press
    200x10%
    which seem better cause you press less keys

    But if I want to calculate 200x10%x30 then it will show 12000 instead of 600
    Now I know I could type 200x0.1x30 and I will get 600
    but then what the point of having % key

    Is there any calculator in wp store that can key in 200x10%x30 and return 600?

    Wow. I remember the day at school I noticed my TI calculator behaving exactly this way. I thought math had failed me. 😊

    Your second approach (*0.1) is how mathematicians/engineers calculate percentages. Why? Because there is no standard way to calculate percentages on calculators. Every calculator does this differently. Casio calculators were particularly curious in their approach.

    Hope you find what you are looking for. Good luck!
