About the Number 8 (eight)

MathBabbler created this BAB shortly after creating a BAB about the number three. With the posting of this BAB, we now have a BAB for each digit of the base-10 number system.

A lying down 8 is the symbol for infinity .

In the computing world, there are typically 8 bits (binary digits) to a byte.

MathBabbler now has a BAB for the 10 digits that comprise the base-10 (decimal) number system. Without digits, there are no numbers and without numbers there would be no number BABs. This is number BAB #32, which is a multiple of 8.

The octal (base-8) number system has 8 digits (0-7).

[Wikipedia] The number 8 is a Fibonacci number and it is the only Fibonacci number that is a perfect cube.

Carl Yastrzemski, one of MathBabbler's favorite baseball players when growing up, wore number 8 while playing for the Boston Redsox.

What did the zero say to the 8? Nice belt.
