My favourite subject is Maths. You will ask me: "Why?". I can easily answer your question. I really enjoy working with numbers, doing sums, counting percents. As for me, Maths is the most important subject. Maths is everywhere in our big and busy life. We couldn't live without it because better part of modern equipment is based on Maths. People count something everywhere - at the bank, shop, work, school and so on. So, I think that everyone must study and know this subject because you will be forced to pass the Maths exam and you just must know it to read the price at shop.
