    Could be. (I did it in my head, and got it right - but I checked it on a calculator! :laugh: ) In the days before barcoded products, I used to add up the prices in my trolley / basket while bored waiting at the checkout, and hand over the exact amount. Even then, I got some strange looks from checkout girls (for they were all females on the checkout in those days) who needed the machine to tell them how much change to give. :sigh:

    (true story) I once went through a checkout line in my local WalMart, and I had to show the cashier how to count out my change.

      At least that's how I felt. I had to perform 371.52 - 60.41 - 64.40. I have a whopping headache so didn't feel like doing it in my head, so I did it old school. With pen and paper. I'm talking without a calculator. I'm not making this up. And I ended up with the right answer. First. Time. Without cheating. The thing that shocked me the most is just how long it's been since I've actually used my brain to work out something as trivial as subtraction. It's actually a little scary. Our kids are screwed.

            I know, but you'd think that counting out change would be one of the minimum required abilities for the job.

                I have a brother who is teaching high school for 'at risk students' (if they don't get help, they will simply drop out). At the end of the school year, an assessment was done of the students to identify where they stood in terms of basics: reading, writing, arithmetic. They discovered the kids didn't know how to add/subtract/multiply/divide without a calculator... so, he will be doing remedial studies for a few weeks so they understand the basics. Oh, and he is the English and History teacher; the Math teacher can't be bothered lowering himself to actually teach the kids.

                  It isn't. You hire something that is not too bad to look at, have someone experienced show them how the big calculator works, presto. Both cheaper and easier; and with all moving to paying with plastic (credit or debit), it is a topic that is easily skipped during the 'on the job training'.

                          I regularly do basic math operations with pen and paper, when it's too complicated to do it by head and fetching a calculator or a computer would be longer than doing it 'the old way'. I'd have done this one by head, however :p

                          while (true) {
                          continue;
                          }

                            I did and still do a lot because when I was a little boy I often "designed" things in my head before falling asleep, now I design other things while I'm on the train or before falling asleep. You know, things as game mechanics (for games tha probably will never be) and... stuff. Things that often involve multiplication, divisions, powers and even square roots (of course I approximate) or areas and volume calculations. I'm credited to be a fast calculator in facts :D

                                  I'm sorry, but you're an idiot. It would have been easier for you to create a dummy (pun intended) profile and posted "need hlp plz" with this and gotten the answer quicker. None of us would have been the wiser. :) P.S. - In the event that you had different answers, you could have created a poll to weigh in on which answer is the most likely. Thereby saving lead and trees. P.P.S. - I hope you use a mechanical pencil sharpener.

                                      If you want a real fright, try doing long division.

                                      A few years ago when recovering from an operation I used to wake up at night several times. Looking at the clock and see it was 4:13 or 23:57. To pass the time I factorized the time as number (413 2357) from the head. Yes European clock, No it was no operation for brain damage :) 413 = 7*59 2357 is prime, note that 2357 consists of 4 consecutive prime numbers/digits. don't know if there are more with 4.

                                        At least that's how I felt. I had to perform 371.52 - 60.41 - 64.40. I have a whopping headache so didn't feel like doing it in my head, so I did it old school. With pen and paper. I'm talking without a calculator. I'm not making this up. And I ended up with the right answer. First. Time. Without cheating. The thing that shocked me the most is just how long it's been since I've actually used my brain to work out something as trivial as subtraction. It's actually a little scary. Our kids are screwed.

                                        took me 5 seconds before I continued reading because I do any mathematical problem when I see it without thinking why would I do it weird!! but I love doing it :)

                                          Clickety[^] I often to paper calculations, just to keep my hand in, so to speak. When I'm developing games, especially, some of the trig I actually enjoy working out on paper much more than just getting the answer from some electronic medium.
