>>9526447>most people (and I mean smart people) wouldn't figure out negative * negative = positive without being taughtI doubt that. You could easily figure it out without instruction by thinking through a specific example, like:
Walking forward one step is 1.
Walking backward one step is -1.
Taking two steps forward three times is 2 * 3 is 6 is six steps forward.
Taking two steps backward three times is -2 * 3 is -6 is six steps backward.
Taking two steps forward reversed three times is 2 * -3 is -6 is six steps backward.
Taking two steps backward reversed three times is -2 * -3 is -6 is six steps forward.
