    Exclamation Calculator Help

    I have a Treo 600 and will soon get a 650. A buddy @ work already has the 650 and this is a problem that we found. On the 600 when you key in 150+15%= you see 150
    15% (22.5)
    =
    172.50

    on the 650 you get 1.65 keying in the same calculation. if you enter 150*15%= it does give you 172.50. Can someone else with a 650 verify this? If you get the same result, I will not worry. If you get a different result, may have him take it back. Why did they change the functionality of the calculator?

    Thank you

    When using a calculator for computations like this, you have to do the "somewhat complicated" function first. So in this case, you calculate the 15% first, then add the 150 to it. The only time you can do that straight foward, i even think it will require parenthesis, is when you use a scientific calculator.

    I don't have a Treo, but shouldn't 150*15% (or .15) return 22.5? If you're calculating tax/tip/etc, shouldn't you multiply by 1.15 to get the total?

    I believe he wants to calculate 150 + 15%. Actually looking at it now, Asmoore's post is a little confusing. Asmoore, what are you trying to do? Add or multiply, and please state it out clearly.

    calculator

    I am trying to add 15% of 150 to it as markup. Again, the big issue is that on the 600 this gave the answer 172.50. He is trying to figure out our cost markup on products for a sales order. I am just wondering why they changed the functionality from the 600 to the 650.

    I finally gave up on the calculator and reverted to my tried and true FinCalc from Landware (www.Landware.com). Great financial calc, especially if you're a HP 12C user.
