All in a day's work

John,

If we are dealing with a mere 1% of the population in instances such as that, we are very fortunate. My estimate is closer to 40% in the population.

Having spent 40 years trying to teach many of the 40% algebra, geometry and trigonometry, physics and basic computer applications, I thought that I was doing a favor for you. No need to resort to faux sarcasm...I can't be insulted...keep it real!

Yourpen pal,

Paul
