👉 The term "columnal" is a term used in the context of mathematics and physics. It refers to a system of linear equations that can be solved using Gaussian elimination or similar techniques. In mathematical terms, a system of linear equations is represented by a matrix, where each entry represents the coefficient of a variable in that row of the matrix. In physics, a columnal system is used to describe how an object's motion is affected by its position and acceleration. The goal is to find a set
