If I am given a formula and I am ignorant of its meaning, it cannot teach me anything, but if I already know it what does the formula teach me?

When I fill, I am alone & a lot of haze in my life. I close myself in a room with a mathematics book. It fills a thrill in my mind..!

M4Math helped me a lot.

Thanks m4 maths for helping to get placed in several companies.
I must recommend this website for placement preparations.
