SUMMARY
The inverse of the sum of two equal-sized matrices, (A+B)^{-1}, is not equal to the sum of their inverses, A^{-1} + B^{-1}. This conclusion is definitive and is supported by matrix theory. The properties of matrix inverses dictate that the relationship does not hold true for general matrices, regardless of their dimensions.
