Algebra is a powerful and rich branch of mathematics that is useful in everyday life as well as business, engineering, and other technical fields.
Besides equations, there are inequalities (less than and greater than). A special type of equation is called the function. This is often used in making graphs. Algebra can be used to solve real problems because the rules of algebra work in real life and numbers can be used to represent the values of real things. Physics, engineering and computer programming are areas that use algebra all the time.
