Add or multiply two 2×2 matrices.
Adds or multiplies two 2×2 matrices. Enter each row separated by ';', values by ','.
Add: element-wise. Multiply: row × column dot products.
Matrices are the standard way to represent linear transformations — rotations, scaling, and more — which is why matrix multiplication shows up constantly in computer graphics, 3D game engines, and machine learning.
[1,2;3,4] × [5,6;7,8] = [19,22;43,50].
Yes — A × B ≠ B × A in general. Matrix multiplication is non-commutative.
This tool handles 2×2 only. For larger, use a spreadsheet or Python/numpy.
Only if the dimensions are compatible — for two 2×2 matrices this is always true, but in general the number of columns in the first matrix must match the number of rows in the second.
