本文通过两个经典的笑话展示了不同数制之间的转换如何成为笑料。首先介绍了一个关于二进制理解的世界观划分，接着解释了为什么数学家会混淆万圣节与圣诞节的原因，涉及八进制与十进制的换算。

There are only 10 types of people in the world: those who understand binary, and those who don't.

This joke relies on the fact that mathematical expressions, just as expressions in natural languages, may have multiple meanings. Like other puns, the humor is derived from an ambiguous meaning; in this case, the expression 10 in the binary numeral system is equal to the decimal number two.

Another pun using different radices, sometimes attributed to computer scientists, asks:

Why do mathematicians always confuse Halloween and Christmas?

Because 31 Oct = 25 Dec.

The humor lies in the similarity of the abbreviation for October/Octal and December/Decimal, and the coincidence that the two representations equal the same amount (31 Octal is 3*8 + 1 = 2*10 + 5 = 25 Decimal).
