I can only recall certain number combinations and I never bothered to do the drills to learn my multiplication tables. I can multiply very basic things (fives, tens, elevens) but aside from that I gotta use a calculator.
Takes me awhile to calculate things in my head and i'm often off by around 5-9 from the actual answer when I do work it out.
I know a bunch of methods of solving things though so if I have a calculator handy I can calculate the stuff I want but mental arithmetics was never something I valued as a kid.
- blarg1 8y agoI actually have a bit of trouble recalling the numbers sometimes, so I tend to rely on what feels right. Like numbers up to a certain point (eg 1-44, 2^(0 to 12)) all feel different to me and some numbers feel related (eg 5,9,45). I have a bunch of methods too though they aren't very good compared to the ones I've seen other people use.
