Okay got one tiny thing thats been bothering me

E |--------------------------------------------------------
B |--------------------------------------------------------
G |--------------------------------------------------------
D |---7----------------------------------------------------
A |---7-------7--------------------------------------------
E |---5-------5--------------------------------------------

Those chords are both "A5" only the first one contains a second "A" an octave above the first one. So, how do you tell what someone means when they say "A5?" Or is the first one called "A5 with an octave?"
