Study Notes
Definition of Algebra
- Algebra is the branch of mathematics that manipulates abstract symbols, rather than numbers, with arithmetic operations.
- It studies algebraic structures and the manipulation of statements within those structures.
Origins of Algebra
- The term "algebra" comes from the Arabic word "al-ŷabr", meaning "reintegration" or "recomposition".
- Algebra has its roots in the history of mathematics, dealing with number theory, geometry, and analysis.
Algebraic Equations
- Examples of algebraic equations include x + y = z and b - 2 = 5.
- Algebraic equations are distinct from arithmetic equations, such as 2 + 3 = 5 and 73 * 46 = 3,358.
Applications of Algebra
- Algebra has numerous applications in representing problems in the form of mathematical expressions.
- It involves variables like x, y, z, and mathematical operations to solve problems.
- Algebra allows for the representation of formal problems in everyday life.
Algebra 1 Course
- The Algebra 1 course, often taught in the 9th grade, covers topics such as:
- Linear equations, inequalities, functions, and graphs.
- Systems of equations and inequalities.
