Really? I struggle to see how dividing any number by two is easier than dividing it by ten, but would like to be enlightened. Divide by ten I just need to mentally move the decimal point, dividing numbers such as 35 or 123 by two requires a lot more mental arithmetic.
- thechao 4y agoIt's 1795, and you're a farmer asked to build a ruler based on divide-by-10, or divide-by-2. Anyone with a compass can do the latter; the former is nearly impossible.
