I am a programmer, so a quick brute-force would easily give me the answer, but I am more interested in a pen-and-paper solution. How many zero digits are there in all six-digit numbers?

The first digit is never zero, but if we pool all of the non-first digits together, no value occurs more often than the others, so exactly one-tenth of them will be zeroes. This solution might appeal to a programmer's mind.

What remains is. However, we may also put a zero in the tens place. Similarly, we may count the zeros in the other places by considering the naturals into which they can be injected.

How about the googolplex , which is a one followed by a googol of zeros. The googolplex is so large its value exceeds the number of atoms in the known universe. Since then, even larger numbers have been described, such as TREE 3. The names given to large numbers based on powers of ten vary between different countries. The two main naming systems are the short scale and the long scale. The United States uses the short scale, in which a billion is 1, million and is written as a one followed by nine zeros.

The long scale is used in France and was previously used in the United Kingdom. In the long scale, a billion means one million million. A Million? A Trillion?
