Linear Algebra: Introduction

linear algebra matrix

As a business professional, you rely on a wide range of mathematical tools, but none are arguably more frequently used than linear algebra and statistics. This is the first post in a series where we’ll explore how linear algebra provides…

Linear Algebra: Field

Linear Algebra: Field

When studying linear algebra, we are continuously faced with the word field. In most cases, we use the set of real numbers, which is an example of a field. But what is a field? A field is a set that…

Subspaces in Linear Algebra

Galaxy representing a subspace inside the universe of a vector space.

A subspace is a subset of a vector space that still behaves like a vector space under the same operations of addition and scalar multiplication (you can find the link to the Vector Space post at the bottom of this…

Linear combinations

What is linear combinations? When we study linear algebra, we keep running into the idea of “linearity” in a few core ways. Each one focuses on a different kind of object: Today, we’ll start with linear combinations. What is a…

Linear Dependence and Linear Independence

A high-angle interior shot of white architectural beams and pillars reflecting on a polished floor, creating a series of parallel and redundant geometric lines like linear dependent set in linear algebra.

In our previous post, we explored Linear Combinations—the art of mixing vectors together to reach new points in space. It showed us what is possible to build. But in mathematics, as in business, just knowing what is possible isn’t enough;…

Understanding the Basis

Stacked black and white blocks forming an upward staircase, representing basis vectors and linear growth in linear algebra

In linear algebra, we often want to find the simplest set of building blocks that can construct every single element in a space without any redundancy. This set is called a Basis. We are going to define a Basis using…
