But I bet they could tell the difference (when they were out collecting food) between a tree with a lot of fruit and a tree with only two or three fruits!
Human intellectual skills develop in relationship to their daily activity. One can't teach math in a vacuum.
And, you know, there is no such thing as 1+1=2. There is such a thing as one apple plus one apple (the apples being in front of us) equals two apples, but 1+1=2 is an incredible abstraction that it must have taken someone like Einstein to be the first to recognize it some millenia ago.
