    I want to delete this but I won't because it's too funny.

    Good lord.

    I will edit it because it's confusing and the human equivalent of data poisoning to leave it as it is.

      When you need to multiply 7*8 do you simply have it memorized, or do you need to add, subtract or otherwise connect it to another math fact that you know better?

      That is do you simply think "56" or are there more thoughts that lead to 56?

      @futurebird I always know it's 42 because that is the answer to life, the universe and everything.

      All other multiplication challenges are a combination of all four listed answers

        @futurebird I hated having to memorize times tables in elementary school. But I got fast at using the parts I did remember. So I would do 7*6 as (6*6)+6. And 8*6 as (6*6)+(2*6). So effectively I just memorized the 2, 5, 10 and square tables and derived everything else by addition and subtraction.

          @futurebird We spent ages learning "times tables" by rote up to 12 (a hangover from the imperial measurement system), so in principle the answer to any small multiplication just springs to mind. Strangely some combinations seem to be unusually tricky to remember, and 7*6 is one of them. Whereas 7*8 is much easier.

            @futurebird I'm too old to not have up to roughly 12x12 (though honestly more like 10x10) memorized. Those nuns at least couldn't apply corporal punishment at my school. Base 2, well that's a professional job skill.

                    @futurebird

                    For certain types of multiplication... I multiply by 10 (or 100), 1000 and so forth, then subtract the smaller number.

                    So 7*8 becomes 70 - 2*7 (14) = 56. Obviously I don't do that with such small numbers, but it does work very well when using larger ones.

                    By converting the answer into two smaller and quicker to answer ones... I get to the answer quicker than some people trying to do the single way.

                          @futurebird I kind of see it straight away but also see the matrix of multiplication in my head as a sort of validation thing at the same time.

                          If that makes sense 🤪

                            @futurebird I have the weirdest thing with this.

                            When I had to learn those multiplications my mom would question me for practice. I always forgot the answer to 7*8.

                            One day we were in the living room and the TV remote was on the table. Remember the numbers on that:
                            1 2 3
                            4 5 6
                            7 8 9

                            So I saw 7 and 8 on there, and the right answer just above. It clicked in my head.

                            So whenever I have to multiply 7 and 8 I see a TV Remote in my head. We don't even own a TV, I havn't had one since 2001.

                              I'm 56 years now, so I had quite a time to learn. But I remember especially this problem to be a hard one for me when I was a child.

                                    @futurebird I had a hard time learning the multiplication tables, especially for 7 and 8. Until I realised I didn't need them 😁. All I needed was to remember 7×8=56. For all other multiplications (up to 10), the other tables would do just fine 😆

                                        @futurebird I have the weirdest thing with this.

                                        When I had to learn those multiplications my mom would question me for practice. I always forgot the answer to 7*8.

                                        One day we were in the living room and the TV remote was on the table. Remember the numbers on that:
                                        1 2 3
                                        4 5 6
                                        7 8 9

                                        So I saw 7 and 8 on there, and the right answer just above. It clicked in my head.

                                        So whenever I have to multiply 7 and 8 I see a TV Remote in my head. We don't even own a TV, I havn't had one since 2001.

                                        @johnnythan @futurebird Similarly, when I have to tell left from right, I think of my the last turn when driving to our local library when I was an infant, because I'd overheard an adult call it a left turn. I _see_ that road every time. I'm 49.

                                          When you need to multiply 7*8 do you simply have it memorized, or do you need to add, subtract or otherwise connect it to another math fact that you know better?

                                          That is do you simply think "56" or are there more thoughts that lead to 56?

                                          @futurebird Edits aside, it's funny how to me 6*7 → 42 at once but 7*6 I need to reorder into 6*7, and same for 8*7 → 56 and 7*8 (note how my "at once" answers don't always have the smaller factor first; it's almost certainly auditory memory).
