Geometric algebra is a type of math that helps us to understand the relationships between shapes. It's good at working with 3D shapes more easily than regular math. It uses algebra but also geometry - the shapes that we learn in school - to figure out things like angles and distances between them. For example, if we had a triangle, geometric algebra could help us figure out the angles between each of the sides. It's a really efficient way to figure out the shapes of things in the world around us!
