Math just isn't my thing. Never has been and likely never will be.

When I was fascinated with IQ testing during my less secure years I self-administered a bunch of tests and always did well and especially with language and spatial relations. There are many different ways or aspects of knowing,

During Air Force basic training I was one of two people in my flight of 48 who scored well enough on a language battery to be offered a choice to get out of my guaranteed contract for computer programming and enter the Defense Language Institute for either Russian or Chinese. Computer programing was considered a critical need in 1980 but apparently language was more critical.

I stuck with computer programming, mainly because the preliminary DLI training was 52 weeks whereas computer programming was only 11. I've been a mainframe computer techie since (1981). Oddly enough my greatest strength in the field isn't my technical expertise, which isn't anything to sneeze at, but a very intuitive approach to the task at hand.

So no disrespect intended but what you posted is all Greek to me.
