Step-by-step explanation:

(+)2=(+)(+)=(+)+(+)=2+++2

Now, here’s where I’m to deviate from what most answers here have done.

What exactly are    and   ? Are they numbers? Or are they other mathematical constructs like say tensors (or more easily understood example being matrices)?

In matrices if we define two variables    and   , then it’s seen that  =/=

(+)2=2+++2
