Ok ladies and gentlemen

my question is probably an easy one to answer  and  the answer will probably be something  that is very obvious but still  i cant figure it out for some reason.

Anyway  the question is     on a few moves   it says  Take  or  they take   +1forward ( +1 forward to what ? )   and  on my brainer  it says   they take -1 right now  ( -1 to what ? )

like i said its probably very easy question  and probably something  i overlooked in the rules somewhere but  still i would very much appriciate the help :)

thnx in advance
