Would a lobotomy help my ADD?

Those are scams anyway.


Why should anyone be amazed that people don't get the order of operations correct, when even simple calculators don't get it right ...

When I come across one of those, it's going straight into the recycling bin

As I've always said: Better a bottle in front of me than a frontal lobotomy.

84-4=80
80x4=320
James calculation would give you 20
16+16+4=36
36-16=20

Hey, thanks for proving my point! Remember that the order of operations is not left to right. Multiplication takes precedence over addition: you do the multiplications first, then add the results. So while you, writing your computer code in a careless moment, may have intended to get 320 as a result, your program really does get 20. And I have to go in and figure out why it's not working right :-(

When I tried explaining order of operations to that girl, I happened to say "multiplication and division before addition and subtraction." She wrote five messages about how there was not division. I responded a couple of times that I never said there was, then started asking her to stop talking about division, then just wanted to stop talking with her period. I ended up removing her from my friends' list. She did not seem to appreciate that.
