I've found an issue with the number game that may or may not be intentional. I've created a way to programmatically create a list of all possible combinations of numbers and evaluate which ones hit the target number, and I've found that, out of any ten given times that you play, there may be one or two answerable ones. I believe that this is due to a very odd order of operations issue that's going on. One of my number game plays with a target number of 288 and numbers 100, 25, 75, 9, 6, 8 and 7 appeared to have only one answer: 100*25/75*9+6-8-7. When I tried this number in game, I was told that I was wrong and that it equaled -9. I've tried everything I can think of, and there's no way that I can think of using that equation to come to -9.

Being lucky and repeating the number game several times will give a problem that does not have any order of operations issues that can then be used. I believe these problems are the ones without side-by-side division and multiplication operations.

It doesn't equal -9 but it's still wrong.

Wouldn't that be 291?

And the correct answer should of been... 25*8+75+7+6 = 288

Should have*

Sorry, but I really can't stand all the "should of" and "would of" creeping all over the net in the recent years (damn you native English speakers, damn you).

Sorry, **could of been.

"could of" is not good native English at all! "Could have" perhaps ...

Deutsche Sprache, schwere Sprache.

It's not wrong depending on what you're using to calculate it. In python and ruby, it's right. In damn near everything else I've tried it on including the regular windows calculator it comes to 291.

Depends what you're using to calculate it with apparently, and no, that's not the right answer. You have to use all of the numbers and only change the mathematical operations between them.
