Math Degree

There are plenty of interests in real life. Things that you take pleasure in doing and something that you would want to get paid for doing. While everyone has different interests I appreciate math. I would like to have a future in math and get a math degree.
Math seems simple but some gurling qualities are required. You have to be good with numbers and equations. Like setting up equations and solving them. For the most part, you would have to major in a math study for four to six years. At least to get a teaching degree rolling. You will have to learn how to handle children if teaching is also in your future.
But my questions are how long will it take to get a full math degree. What kinds of math needs to be studied to be sucsseful. And what techniques are used to complete a math degree.
