Hello Gautham,

It's Simple and difficult also. If You want to know something new and create something new, Mathematics will help you a lot. Also, If you like to apply a law or create a law, Mathematics will help you. But, If you want to relax and if you like to remembering something rather than know the actual thing, Biology will help you.Also, if you like to know the behaviour of animals and plants, biology is the best. If You want to be a Physicist, or chemists, Mathematics is the best. Because it is the key for Physics and chemistry also. But for Physics it is the most. Because every problem in physics need a good solution and mathematics will give you the right decision how to get the correct solution. Besides, if you want to invent or discover something and want to give that thing to the people, mathematics will help you. But, if you have a desire to serve someone, then biology will help you. Finally, yet though some machine were not discovered, some medical treatment is also not possible, if you want to make it, go through mathematics and then technical .Aim for biomedical engineering, you don't have to choose at all then. Take both,if you are really interested in both the subjects actually, then you might just be able to handle them both with a smile.
