👉 Row math, or matrix algebra, is a branch of mathematics that deals with matrices, which are rectangular arrays of numbers, symbols, or expressions arranged in rows and columns. It extends basic arithmetic operations to these multidimensional arrays, allowing for efficient manipulation and solution of systems of linear equations. Key operations include matrix addition, subtraction, multiplication, and finding inverses or determinants. Row operations like swapping rows, scaling rows, and adding multiples of one row to another are used to simplify matrices, making it easier to solve equations like Ax = b, where A is a matrix, x is the vector of unknowns, and b is a known vector. This powerful tool finds applications in various fields, including physics, engineering, computer science, and economics, for tasks like data analysis, machine learning, and solving complex systems of equations.
