Matrix Addition and Scalar Multiplication

Once you know what a matrix is, the next step is doing arithmetic with one. This quiz covers matrix addition and subtraction, multiplication by a scalar, and the dimension rule that decides when addition is allowed at all.

Questions mix short conceptual checks with real calculations on 2×2 and 2×3 matrices, so you find out not just whether you remember the rules but whether you can apply them without slipping on a sign.

A natural follow-up to Matrices Basics, and the groundwork for everything that comes after.
