This Rust program shows how to solve a system of linear equations using matrix inversion using the nalgebra library. It takes a $2\times2$ coefficient matrix and a 2-dimensional result vector, then ...

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...

Multiplies ( A^{-1} ) with ( B ) to obtain the solution vector ( X ). Provides error handling for cases where the matrix ( A ) is not invertible or input is invalid.
