Does anyone else remember this “Human Calculator” manner of doing simple math equations? By simple I mean multiplication, division,addition and subtraction. If recall properly, children of ages six to ten would figure out 237 times 71 faster than the talk show hosts could do it on a calculator. It was done by manipulating your fingers up and down and then reading the position they were in after the calculation.
Okay, that was a pretty bad description, but, think of Chismbop (I think that was the teacher’s name- maybe) as being a human abacus. I have searched Google, but it was not any real help.
If anyone has information on it, I would love to see it.
