goddess of wisdom and skill. Plato's motives for making this inscription are not recorded but he clearly felt that
an educated person needed to know mathematics.
When am I going to use this crap?
-a typical exclamation from a student who is not putting in the hours needed
to pass his one required math class.
The answer to the question above may well be "never". That doesn't mean the person who asked the question
wouldn't benefit from basic mathematics. They could have benefitted from math, and its sister quantitative
reasoning, but have chosen not to. There are only a few gainful activities where math is not present. The
innumerate (this is the mathematical analog to illiterate) typically don't notice that their disability is harmful.
They do get cheated, lied to successfully, and ripped off more often than other people. They also don't get
promoted as often or paid as much. Mathematical skill also acts as a leveler between the sexes.
