Math is one of the basic sciences of life; it can be said that is the most basic science, the first thing a person learns, apart from reading and writing, is how to add and subtract. But, is math a part of nature, or was it made to measure or understand nature? It is really hard to know, but in my point of view, math is a method created by men to measure nature. If math was a part of nature, man would be born with math knowledge, but man is not, man had to think about a way to count and measure things. And if it was a part of nature, man would learn it just by existing, but man has to go to classes or special curses to learn math. My way of seeing it, is that science in general is a way to explain and measure nature, but it is growing everyday, because everyday man is discovering more things about nature and all things that surround man. Nature will keep growing until man stops living because nature is infinite, as well as explanations for nature, or science. .
Math can be said to be the most unspecific way of measuring nature, because physics, for example, measures forces; chemistry measure the components of nature. Math is only numbers, basically, it can only say that there is two liters of water. Physics can say the force that water is applying on the ground. Chemistry can say that water is changing the structure of the land, and how the structure of the water itself is changing.
In conclusion, math is only a method to measure nature, a way of giving us a small idea of how big is nature is. The problem is that math will never give us a even close number for nature, because nature can not be measured, nature can only exist as it is.
