KurtagagWhat was a fact taught to you in school that has been proven false during your lifetime?
kingthrillgoreTaste buds are arranged by flavor in four sections of the tongue. Complete load of horseshit.
The multiplication table is still fact even if you have a calculator.
6 x 6 mothefuckers. Y’all tell me that didn’t immediately form “36” in your brain.
SonotsugipaaNope, went through “(6 × 5) + 6”. Slightly slower, but much more flexible since you can do that with any (base 10 representation of a) number that has a reasonable number of digits.
LainTrainWhat? How is multiplying by 5 more convenient than any other number?
When dealing with base 10 representations, multiplying by 10 is a simple matter of adding zeroes;
dividing numbers that end with a zero is (usually) an afterthought;
doing both operations in that sequence is the same thing is (usually) equally trivial, the only effortful thing I have to do is adding or subtracting a multiplicand, once or twice or thrice.
It’s not easier than having the result imprinted in my memory, but it cuts away ~ three quarters of the table.
