Welcome to Algebra!!!
Math is the least popular school subject; because it constantly involves learning entirely new ways of thinking about things, it provides more of a mental challenge than most people care for. However, algebra is such a large part of our daily lives that is important for everyone to understand. So what are the applications of high school algebra? Exactly why is algebra important?
Chances are you're going to need algebra. Obviously the hard sciences (such as physics and chemistry) are extremely mathematical, but you might not realize how much other fields depend on math as well. Computer science? You need algebra to analyze how quickly programs run. Psychology? Requires statistics, which comes after algebra. Art? Algebra is useful to calculate the correct proportions which will lead to an aesthetically pleasing result. Music? The underlying structures of music are basically mathematical.
This is a first year algebra course in which you will learn to reason symbolically. The key content involves writing, solving, and graphing linear and quadratic equations, including systems of two linear equations in two unknowns. Quadratic equations are solved by factoring, completing the square, graphically, or by application of the quadratic formula. The course also includes study of monomial and polynomial expressions, inequalities, exponents, functions, rational expressions, ratio, and proportion. Algebraic skills are applied in a wide variety of problem-solving situations.
