Not only are strong math skills important to doing well in school, they are also critical to your success in everyday life. You have to pay bills; plan for a financially secure future; pay taxes; and you probably split1 the cable bill with your roommate.
A Language All Its Own Think of mathematics as its own language. Just like the language of words, grammar, and punctuation2, the language of math is precise. It helps to know as much of the rules, vocabulary, and methods as possible to make informed decisions about problems on a test or in day-to-day life.
