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?

I will edit it because it's confusing and the human equivalent of data poisoning to leave it as it is.
@futurebird @troberts
I think you'll need to start over with a new poll. Your data is skewed because some people responded "other" before you edited the question. -
@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.
@johnnythan @futurebird outstanding.

That is do you simply think "56" or are there more thoughts that lead to 56?
I first remembered it by recognizing that it's
5, 6, 7, 8
But now it's just an echo in my head.

@Anomnomnomaly @futurebird Theese things get me going...
It's worth pointing out that I wasn't 'taught' this method by anyone... I simply discovered it naturally and started using it.

We also memorised up to 12 x 12 despite being a country that uses the metric system.
@passenger @danielaKay @kbm0 @futurebird
Most multiplication tables go up to 12 × 12 regardless of regional measurement systems. There is nothing inherently special about 12 in the imperial system (or whatever non-metric is called). Most clocks go up to 12 and people often refer to dozens. -

@futurebird I have a learning disability that was never adequately addressed. I can do arithmetic only with a calculator. I have immense difficulty recalling equation strings I'm supposed to know, and I canNot conceptualize numbers in my head of more than about 5. I have aphantasia and cannot 'see' in my mind, and I actually organize most by a system of spacial relations I find difficult to explain. Oddly, I still passed Calc3 in Uni, due largely to its spacial nature and a graphing TI hehe.

@futurebird
When I was a kid learning the multiplication table, it was not easy for me. Probably because I wasn't paying attention. Some facts came easy, though. I don't know why, but 7×8 was one of my favorites. (Yes, I liked some more than others.) Eventually, it all just clicked and it all became easy for me. That must've been the day I finally paid attention. -
@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
-
@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.
@3janeTA @futurebird I think to myself, "You get five-six from seven (times) eight." It works for me but my kids didn't seem to like that method when I tried to help them with multiplication.

@futurebird We were relentlessly drilled on this in 2nd grade (I wear the "privately schooled" badge of shame). I still have some of the worksheets...

@futurebird mathematically challenged, I think: 4*7*2

@futurebird my classmates and I were forced to learn the multiplication tables in grade school. The answer 56 is straight memorization, no math involved.

@futurebird For some reason I developed a HATRED for rote memorization of times tables in school. As long as I understood the concepts of how to multiply, why did I have to memorize so many answers, and calculators already existed and were clearly going to become cheaper and more common, and if I didn't have one I could figure it out in a minute anyways.

@futurebird I had a lot of trouble remembering this for school when I was 8. Now it's stuck in my head forever. With some other multiplications I do some addition or subtraction

@futurebird i thought 7x7 =49 + 7.

@Anomnomnomaly @futurebird And THAT, just THAT is key to human collective understanding. A GOOD school will applaud that intellectual journey. Unfortunately most edu systems uses math/hard science to teach obediance. I had my way of doing division, the REAL teacher gave me creds (5 of 5).
Then next term another "teatcher" went mainstream an gave me grade 1 for being who i was; that is using my own method. Because i could not LEARN to use the laddder (or some such bs). Fascism, actually. -

@futurebird
7*8 in particular, I have to work out. I'd probably go 70 (7*10) less 14 (7*2, to get to tines
to get to 56. For many other pairs I have tricks already memorized, shortcuts to look up the right answer.

@futurebird 7*2*2*2 is what I capsulat calculate

@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.
@KennyPark @johnnythan @futurebird
To be absolutely certain about left vs. right, I start to pick up an imaginary pair of scissors. I know I use my right hand to do that.
I found that 'trick' in like 1st grade. I have since worked in jobs that use analytic geometry and multi-variable calculus. I have debugged issues arising from using a left-handed coordinate system instead of the standard right-handed one. I still have to reach for the scissors.
