God is the Source of reality; like a Universal Central Processor (CPU) in a universal supercomputer.

The problem if the CPU changes the formulation of 1+1=3, is that then the whole reality would take that course, and everything would have to add up that way.

Therefore God is omnipotent; yet God calculates everything for the greater good, and changing the maths so drastically, would destroy much of the life already existing.
