Confuse your friends with this phrase on your T-shirt: There are only 10 types of people ...

There are only 10 types of people. Those who understand binary and those who don't.

This is the T-shirt for nerds. Not only for man, also for woman.

Who understands binary math?
In binary mathematics and in computers there are only two states: zero or one, 0 or 1.
So the 0 stands for the 0.
The 1 for the 1 does not make any difference between the binary and the decimal number system.
But the 2 is written as 10 in the binary number system. While in the decimal number system the sequence of 1 and 0 has the value ten.

I hope I was able to explain it clearly to the computer layman.
