My brother and I each... vs. My brother and I all...

Hi teachers,

Please see the following:

[color=blue]My brother and I each have our own room.
My brother and I all have our own room.

What is the difference between the two?

Thanks in advance



Your sentences:

. This means each one of the two of us -‘both’

This would not work because ‘all’ would only be used for at least more than two.
