Hi

My son Max, age 6 (first grade) has a question:

What comes after undecillion?

Thanks!

Steph



Hi Steph,

I assume that you looked at Billions and more!, the list we have from an earlier question. I went back to the Webster's Third New International Dictionary, G. & C. Merriam Co., Springfield, Mass. 1967, and here is the rest of the table that they have. I only completed the American system.
