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 when I was little I hated math and did everything to get out of doing any math. So I memorized the times tables, which I guess must have seemed easier? Anyway I remember being able to recite the correct answer quickly when it was just numbers, but being stumped when it was a word problem with apples or whatever.
@futurebird I know my squares, so I do 7*7 and then add 7.
@futurebird I will admit to doing 7×7 in my head and then adding seven!
ohk im happy with the poll result, im also one of those that have some basic math thingies memorized and not really do any math to figure it out... phew!
@futurebird
Memorized, sure, but that particular product takes me a second to remember it.
@futurebird 4*14, maybe?
I have a lot of anchor points in the times table memorized and 7*7 and 8*8 are two of them. I use them to get to the close by result quickly
@futurebird I don't instantly know what 7*8 is, but I do know what 8*7 is.
The bigger question is: are the hardest ones 6*7, 7*8, and 8*9 just for me, or for most people? And why?
Mostly I have that one memorized. Otherwise, I decompose it into 5*8 + 2*8, which is 40 + 16.
I have dyscalculia; rote learning the tables is the only reason I can come up with the answer instantly.
@futurebird 7*2*2*2 is what I capsulate
@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 7×8 = 5×8 + 2×8 = (10×8)/2 + 2×8 = 80/2 + 8 + 8 = 40 + 16 = 56
easy
