How old are you?
I am 40 years old... 4 years USAF and 3 years US Army.. During my Army career, I was 13E.. I had to make the calculations for each of the 8 artillery guns I was responsible for to hit their target.. (in less than 53 seconds).. and it was NOT an easy task.. Earth rotation.. humidity (moisture), wind speed, elevation.. etc...
I started programming (98% math) around about 1985...
Oh, I forgot to mention I HATE math :/
In the US Army (actually because of my ASFAB score), I didn’t have much choice in what career.. I would have chosen snipe school.. but my math score was too high :/ for what they were asking for at the time.. go figure)
