(How was someone like me, using 4th Grade Math, able to spot the Original Mistake and Solves the Problem…???)There are people who haven't had much formal education and yet have more knowledge than some who have dedicated a lot of time to studying. Sometimes life itself gives people more knowledge than what is learned in universities.
I have a friend who is 86 years old. This gentleman can tell when it's going to rain and when it's not, and nowadays there isn't a device as accurate as this man.
