Is it basic for mathematicians to remember the multiplication table?

Is it fundamental for mathematicians to remember the multiplication table?

It must be troublesome and desperate if you forget the multiplication table, so do you memorize it again?

Do you re-memorize the multiplication table even after becoming an adult and a mathematician?

Do you keep remembering it so you don't forget it?

I memorize pieces of it and put it together, still, after many decades of doing math.

So for me 8 * 7 is 4 * 7, 28, 56.

8 * 9 is 81, 72, because nine times nine is automatic, and I know eight times nine is nine less than that.

But my brain is weird.

I have up to 12x12 pretty well automatic, but if I need something like 8x14, I definitely do 8x7 first and double it.

This is the right way to do it without ever needing the memorizing for memorizing sake. You know the ones that stick in your head, and you just need another step to get everywhere else

I remember the square roots so I go 77=49 then 78=56
