Mathematics is the language of the universe. It also helps other fields like physics ,chemistry etc. When something is proved mathematically it is considered as truth. Everything around us (don’t know about the emotions, experiences etc) can be put into mathematical equations. Even the football has an equation!
But it is not likely that everyone is going to study mathematics ( in higher studies). Still it never leaves anyone alone. If we don’t know basics of mathematics ie numbers and simple calculations, we cannot survive in this world. The concept of 1,2,3… may seem to be so simple, but imagine a day without these. Even total no of members of family, your phone, cycle, car etc etc is basically mathematics.
