Because of Al-Kwarazimi. Hindu-Arabic math is base 10 and Al-Kwarazimi developed a really good method for doing math as well as inventing algebra. Base 10 spread with his methods. It looks like the Chinese were also using base 10 as far back as during the Shang dynasty. Meanwhile Europeans and their cultural descendants still use base 5 for ceremonial purposes (yes, even in MMXXV)
As an engineer life would be easier if we all thought in base 12, for my wife as a computer scientist life would be easier if it was in 2^n. 10 is a really convenient sized number for arithmetic and algebra though. Babylon was insane i genuinely can’t imagine trying to teach children the name and order of 60 digits to the point of instinctive mathematical understanding
All maths is done in base 10.
