The mathematical genius behind this sandwich is *chef's kiss*! When you multiply matrices, you're essentially creating all possible combinations of their elements. Just like this PB&J 2.0 with its 3 rows (jam, honey, marshmallow) and 3 columns (crunchy, Nutella, creamy) creating 9 glorious flavor combinations!

In matrix multiplication, a 3×1 matrix (a column with 3 elements) times a 1×3 matrix (a row with 3 elements) gives you a 3×3 matrix with 9 elements - exactly like this culinary mathematical masterpiece! It's the tastiest way to visualize the outer product in linear algebra I've ever seen!
