Sorry, I saw that now.

My best answer: I am a formalist, basically that means math is a game invented by humans and does not or may exist elsewhere. It is not built into the universe as the Platonist believe. The rules were and are invented by man.

I agree. We have ten fingers and our math is in base ten. Who knows? Somewhere else it could be in binary.

It would be different from when it was coloured. If the beta-carotene was transparent it's whole chemical structure would be different

Hmm... Could you give me an example on how the pyramid should look like?

Numbers below 10?
The prime factors of 150 is 1 x 2 x 3 x 5 x 5

Carrots are orange in colour because of beta-carotene. Beta-carotene is a precursor of vitamin A.

Transparent carrot won't be that healty as it does not contain beta-carotene.
