Mathematics occupies key place in our modem civilization. It is ranked as one of the great realms of human intellectual achievement. It is a by-product of our empirical knowledge. Scientific knowledge tallies with the actual phenomena of nature. Scientific study reveals that a particular phenomenon of nature is basically structured and that there is systematic relationship between these structured aspects of phenomenon. This can be precisely stated in exact quantities and these relationships can be precisely stated in mathematical equations.I focus on imparting simple but systematic skill in students for them to efficiently think critically.
