Buggy app!

So, the equation of: 6-1x0+2/2=7 because if you take order of operations itd read this way: 6-(1x0)+(2/2). Broken down it would look like this: 6-(0)+(1). 6-0 is 6 and 6+1=7. Well, this app comes up with 6! I "played" the solution and it completely ignores the fact that theres a zero in the equation!
Heres the kicker: I email these guys and explain that their app came up with the wrong answer. They tell me its a bug in their software (Really?!?) and theyd fix it soon. I waited a few months and checked the equation again, same answer. So I waited a few more months (checked it just now) - *still* the same answer!!!
I think that they have absolutely NO intention of fixing this bug! IMHO, its not worth your time or money. Find one that will work.
