A comment on Learning math? Think like a cartoonist.
If we instead start with a negative number, multiplication will make the number bigger.
If we allow for any integer, multiplication on average, will neither be biased one way or another.
It's a bit of a carny trick to hide the bias in the selection of only positive numbers, and then act like multiplication itself has the issue..
This leads me to believe the author doesn't know math very well and their learning techniques are not efficient or worth giving credence to.
If you give an analogy to explain a concept, it shouldn't be fast one, it should be honest!
