         1. The most important subjects that we study in school is mathematics. If we do not know how to do simple arithmetic when we do some everyday kind of activity like go to the grocery store, we will not be able to keep track of our personal accounts without going bankrupt. Many people are poor not because they do not earn enough money, but because they don’t understand the mathematics behind finances.Besides the importance that mathematics has in our financial lives, it is also important in many other parts of our lives. For example, in the kitchen we have to know about mathematics functions like fractions or multiplication. Sometimes we cut amounts in half because fewer people are being cooked for or we have to double or triple amounts if a lot people are coming over to visit us for a special occasion.
