Dear Students,
Welcome to your Mathematics and Religion Classes.
I am happy to work with you this academic year. I know you are very ready to dissolve the real world problems through your basic skills and careful applications of Mathematical concepts by June 2020. Be ready to find Math and Religion in every corner of your environment. From the Religion class, you gain confidence and God’s blessings for the mathematical adventure.
Welcome aboard the train of success!
