The more you spend on me, the more I can give back. I can build people's futures or I can break their backs. What am I?

As I was going to St Ives, I met a man with seven wives. Each wife had seven sacks, each sack had seven cats, each cat had seven kits. Kits, cats, sacks, wives How many going to St Ives?

The more you know the faster I get, I'm said to be bliss, I do not excuse you from the law

I have twenty-four faces, it’s hard to believe. When you look at me I have sixteen vertices. Eight cubes when unfolded in this reality. Thirty-two edges is quite the sight to see.

I am born when nothing divides, yet found in all that lives and dies. I have no weight, but tip the scale, the silent glitch in every law. You seek to name me, but beware, to know me is to say I'm not there.
