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?
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 Good question. Also, what is the answer to the ultimate question of life, the universe, and everything?
@futurebird Ah you edited. Now I look like an idiot. It was bad enough just being one.

@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 9So 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 just remember the words. Like a song or a poem. Math was never a favorite subject.

I thought about leaving it, but it seemed too confusing.

@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 ...the first poll option still says 7*6 for me

@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.

@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).

@futurebird when I was in elementary school, our teacher started every day with handing out a piece of paper, that we folded into a grid pattern and filled in the table 1-10 across the top row and left column. And then timed our filling out the rest. It was memory training.

@futurebird I get to 56 eventually, the times tables are one of the few things that are worth rote learning, as knowing the answer instantly are really useful

@futurebird I guess we assume the decimal system. I always assume most people have a internal lookup table for multiplications with results under 1000

@futurebird I think “7 times 8 is 56” because for some reason that’s how I memorized the multiplication tables. Almost got me in trouble with the other third graders in a “multiplication bee” where I was destroying them but whispering the first part under my breath.

Off topic, but why does Mastodon offer two things to click on if it's only been edited once?
V confusing.

@futurebird I have this one specifically memorized because it’s the times table that Molly the American Girl gets wrong in one of the books and 9-year-old me was like “that will never be me, I will commit 56 to memory like it’s my home address” and so it has been ever since

@futurebird 6*7 is 42, which I have memorized like most of the multiplications up to 12*12.
But 9*6 = 54 is one I can never remember on its own. I always go 8*6 and then add 6.
@aesthr @futurebird the 9s are easy though! Because it’s whatever the non-9 number is (6) minus 1, so 5, then make it add up to 9 (5+4=9). I have no idea why this is easier for my brain than any other addition/subtraction
