My Momma and I are pretending to go to new earth and before we go we need these things:

Gardening stuff like seeds

Farm animals including horses for transportation

Math books

Science books

and more

One of the things we need is a number system.

I want your opinion.

Should we use base 10, base 12, base 20, or base 60?

If we use base 10 should we use roman numerals( () for * 100, - above or below letter for * 1000, combinations for multiplying by any other power greater than 10^1), Greek numerals, Egyptian numerals, or Hindu-Arabic numerals?
