There’s seems to be a concensus among different mathematicians that two negatives multiplied together should equal a positive. For instance, the Indian mathematician Brahmagupta also came to this conclusion, apparently independently, in the 17th century:
“The product or quotient of two debts is one fortune.”
So there must be something handy about this, that shows up when you are
working on math problems. That’s fine with me- but what is it?
