I learned a lot of crap in school and retained it only to the next test. Ask your mother if she knows what scientific notation is.
Well, I guess anyone who is incapable of learning a few prefixes does not have much economic value anyway. So I don't mind if these people don't use bitcoin.
PS. If I ask my mother what scientific notation is, she will obviously say she has no idea. But if I ask her how many millimeters there are in on meter, I'm pretty sure she'll have to give it about 10 seconds thought, but hopefully she'll come out with the right answer.
