Question

i used to really good at net loss and gain but i havent done it in a while can someone help

Answer 1

errr..........net is simply the effective portion. Just like you git $10 but you owe $2. Even though you got $10, the amount that is truly yours is 10-2 = 8. This your 'net'.
Simply expand this to profit and loss.

Answer 2

thanks

Answer 3

you welcome. Gross on the other hand is the total with respect to your angle of observation. Gross would be $10 if looking at cash at hand.
