I checked your math for you old man. I know they didn't have calculators or algebra when you graduated high school, so this could be a difficult subject.
Maybe you should sit out actually. Using your brain this might could hurt you.
This silent generation faggot is so senile he not only forgot everything he learned in his education , he even forgot what education is.
Let this Millennial give your 95 year old ass a history lesson.
Algebra was first proposed in Al Khawazami's book
Kitab al-mukhtasar fi hisab al-jabr wal-muqabala 850 AD give or take and the Rene Descartes's book
La Géométrie introduced modern algebric concepts.
Its not a 50 year old concept you senile granpa :cheers:
