tiger calculator

Ok this may be the stupidest question ever but i can't figure it out. Basically i do a lot of math involving percentages. So when i have the Calc in Scientific before i could punch in say 500+10 then hit the % button which would then show 50 and then i could hit enter and get a total of 550. But...somehow something has changed so that now when i enter 500+10 add hit the percentage button it changes to .1 and then hit enter i get 500.1 so how do i adjust this within the program? Anyone know?

Basically, you'd need to type 500 (M+) * 10% (enter)(M+)(MR).

It's an order of operations thing.

well yeah i can do it that way but don't want to. I was doing it the way that i typed...and oddly enough, i can still do it on my desktop...but not my laptop so there's got to be a setting calc option that changes this, i just can't find it.

I don't recall I've ever used any other calculator that behaves in a manner such that:

500 + 10 % = 550.

It strikes me that if one adheres to strict orders of operations, 10% is evaluated (to 0.1) before the addition. So, 500.1 is technically the correct answer.

Then again, I really don't use the percent key. Through all of my math courses, I've always been used to just using decimals to represent percentages. So, 500 + 10% becomes 500 * 1.1. The logic is much cleaner as there is nothing implied. That helps a lot when the math gets really thick.

oh i know exactly what you mean, i noticed the calc was doing it and that's when i started using it more...saved me the trouble of converting everything to decimals, i would have to guess it's some sort of option that you can turn on and off and sort of sidestep the usual rules. It's seriously useful so i'd love to get it figured out.
