    Would this be a bad time to point out that that's arithmetic and not really mathematics at all then?

    I have a passing knowledge of the topic.

      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.

      So... did you calculate 371.52 - 60.41 - 64.40 or (371.52 - 60.41) - 64.40?

        Took me a couple minutes, but just did it in my head... That took way too much effort. 52 - 41 = 11... 371 - 60 = 311... 311.11... 11 - 40 = -29, so 310.71 - 64... 300.71 - 54... 250.71 - 4... 246.71. Pen and paper may have been quicker.

                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.

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

                        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;
                                      }

                                        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:

                                        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

                                          Would this be a bad time to point out that that's arithmetic and not really mathematics at all then?

                                          Don't be so integralist about it, why differentiate so much when it's a simple derivation!
