maybe the kids on the streets aren’t able to multiply—they “memorise” the whole thing (3x2 =6; 3x3 = 9, etc.) to make the transactions faster.
Well, multiplication is done largely by memory for everyone for small numbers. There’s a lot of evidence for this, such as fMRI studies showing memory related areas of the brain being active during multiplication that aren’t active during addition. Also people with strokes who then lose the ability to multiply almost always have other memory impairments. If the kids on the street are using memorization then they are doing the same thing as everyone else.
