Re: There are 2^256 private keys out there: how big is that number?
Once people understand what it takes to reduce a number with 156 zeros down to a manageable size, they usually begin to comprehend why "I'm thinking of a random number" is actually a very safe way to store your Bitcoins.
This is actually the point of this whole thread!

Here's another snippet of wisdom from when I'm trying to explain the odds of guessing a private key:
Cheat code to convert 2^x to 10^x: reduce the exponent by 3 or 4 (2^3 = 8; 2^4 = 16)
2^160 is (roughly) the same as a 1 with 156 zeros.

No. You have to divide 160 by 3 or 4.
2^160 = 1461501637330902918203684832716283019655932542976
like 1 with 48 zeroes.
After a thoroughful research I can confirm @arulbero result:
