Zero was invented about 4,500 years ago when the slaves were

building the pyramids. They would keep track of their weekly salary

and at the end of the year the grand total would be equal to seroh,

seroh being ancient Arab word for nothing. The symbol 0 started

being used during conversations when the various slaves were

asked how they were doing financially at which point they would make a circle with their thumb and forefinger to demonstrate.

The phrase "Take this job and shove it" also started during this period.
