After reading the entire post all 33 pages it's not clear for normal people how YOU explain it, of course for you it's ok and for some is a bit confusing due to your short term of explaining we the normal people know exactly what mirrors are and sums and roots and+-x and even ÷ BUT you take it to another level like everyone else knows what you are talking about. And we appreciate you for posting this to be shared with us, but come-on is human sense of trying to help and get through a better explanation and then i noticed that you tried to make easy on the second explanation BUT you didn't have good sense of trying the easiest way this by far is one of the most complicated threads i seen here not for not understanding it but for making it more complicated, WHY not take a little bit of time and say.... Here's the soup, 2+2 is 4. But in my case in this explanation 2+2 is 7 because i learned that doin this 2 gets on the road and the other 2 comes driving a car with 3 wheels and bammm wrecked the other 2 and that makes a 7. Easy explanation. nooooo you wil cone with 2mt=9 mirror 4 them total is 9. 😂 Lol. I know is frustrating but come-on take some time and explain each other number slowly not making it more complicated. We all loved you we all have a great reason to be together on this forum for years and years why not ? Remember doing things like ily. Doesn't read i love you it means what the heck that means. Of course you know what but come-on not everyone. Anyways thanks for the post even if i still don't understand it.
