# Determinants

Determinants are special numbers found by doing special calculations within Matrices. They have powerful applications in advanced math topics in Algebra 2 and Calculus, especially when dealing with polynomials, systems of equations, and even integrals. You will learn how to find 2 x 2 Determinants, 3 x 3 Determinants, and others. Challenge yourself with concepts such as Sarrus' Rule and Laplace Expansion to calculate determinants of larger matrices. After practicing how to calculate determinants in sub-topics Determinant of a Triangular Matrix and Determinant of Interchanged Rows, you will be prepared to evaluate if a system of equations has infinite solutions, or if it has no solutions at all. By mastering granular concepts such as these you will strenthen the critical thinking skills ncessary for further advancement within Algebra 2.
