A rectangular array of real numbers that can be used to solve a system of linear equations is called a(n): Square Array Matrix Elimination Method Element

A matrix is like a superhero in the world of mathematics! It's a rectangular array that holds numbers, and it comes to the rescue when solving systems of linear equations. Matrices can transform complicated equations into simpler formats, making them an essential tool in linear algebra and beyond, from computer graphics to data analysis. To get the most out of matrices, avoid common pitfalls like confusing rows and columns or forgetting to check the dimensions when adding or multiplying them. Remember, not all matrices can be multiplied together! Ensuring that the inner dimensions match will save you from many headaches. Happy matrix multiplying!
