Nonlinear algebra is a branch of mathematics that deals with systems of equations that are not linear. While linear algebra focuses on linear systems, characterized by linear equations (which can be expressed in the form \(Ax = b\), where \(A\) is a matrix, \(x\) is a vector of variables, and \(b\) is a constant vector), nonlinear algebra involves the study of equations where the relationships between variables are nonlinear.
