answer:Good question, not sure. If a child grew up with no basic mathematical training, 1+1=2 etc. I am sure, the human child would, eventually, make associations with the amounts of particular items, but…with no concept of numbers there would really be no association beyond visual computing. Obviously a pile of a dozen eggs, or buffalo hides or apples would be assimilated on a mental level as more than one but without actual symbolic numbers to denote actual and accurate accounting I don’t think true mathematical ability would evolve out of nowhere. More than likely it would be along the lines of a particular vessel or basket or whatever container that would either be completely full or half full etc. In other words, a human, primitive or otherwise might invent a mathematical system but not have an actual ability to count so it would be more measurement based I would think. A turtle shell full of berries in trade for a turtle shell full of acorns, that sort of thing. Look at how little children think that 10 pennies are “more” than one Dime. haha
