Math Help - complexcity defined

1. complexcity defined

State true or false? gicve reason?
If A and B are two matrices such that AB is defined, then A+ B will be defined?

Ans) If we take any combination it can we proved. But what about complex numbers. Are complex numbers defined.

Think logically,learn magically.

2. The Number set is of no consequence. Matrix addition and matrix multiplication are not defined in any way that distinguishes Real from Complex. Note that Real ARE Complex...

Think about conformability. You can multiply (mxn)(nxr), but can you add them?
