Algebra Algebra is a branch of mathematics that help us in the representation of problems or situations in the form of mathematical expressions. All the branches of mathematics such as trigonometry, calculus, and coordinate geometry, involve the use of algebra. Algebra encompasses a wide range of topics, including solving equations, understanding functions, and working with […]
