    What the actual fork have they done to maths?!

    My son is in Year 6 and I think in old money it would be called long division but I have just been shown "the bus stop method" and although it works, it just seems crazy!

    I have always been rubbish at long division. How does this method work?

      Looks like it is just long division but skipping the part where you show your workings so relies on better mental arithmetic.

        You tap the person in front of you in the queue and ask them to do it...

          The bus stop method seems to be just long division with carry (or something like that) that I learnt decades ago.

          This one is popular and new. I was taught it by a trainee teacher last year.

          Of the Japanese method I thought well that is interesting and my youngest understood it.

            According to Twinkl, that method is “short division”:

              As explained to me, you find the biggest number that can be divided by the divisor, sub tract that from the total and keep going, so the question we have just done.


              Code:
              8729 / 7
              
              
              subtract 7707 (1101 * 7)
              
              1022
              
              subtract 700 (100 * 7)
              
              322
              
              subtract 210 (30 * 7
              
              122
              
              subtract 70 (10 * 7)
              
              42
              
              subtract 42 (6 * 7)
              
              1101 + 100 + 30 + 10 + 6 = 1247
              Which gives the right answer

                I follow the scootie contrarian method of long multiplication.

                  Interesting .... seems an overly complicated way of doing long division.

                  Sometimes, if it ain't broke, don't fix it

                  And where's the graph, or it didn't happen

                    That's not long division, just division.

                    Long division is 9829 / 71 - or when both numbers in the sum are more than one digit long and usually more (or greater than the highest multiplication table you already know). Same technique though, just takes a bit longer
