Matrix Calculator
Add or subtract two 2×2 matrices.
Worth Knowing
Matrix addition and subtraction work entry by entry, so both matrices must be the same size — there's no clever shortcut, just element-wise arithmetic. This is the gentle end of matrix operations; the behavior that makes matrices powerful and occasionally counterintuitive shows up in multiplication, not addition. Adding matrices is commutative just like ordinary numbers, which is emphatically not true once you move on to multiplying them.
