Llevar and traer are two verbs that if we translate them into English, both would mean to bring, yes yes both mean the same!!!. but there is a difference, we use Llevar when we are going to bring something from we are right now to another place and we use traer when we are going to bring something from another place to the place that we are right now.
Let's see some examples:
Mañana es el aniversario de Ana y le llevaré un regalo
(tomorrow is the Ana's birthday and I'll bring her a present)
Vienes a la fiesta de Ana? traes algo?
(Are you coming to the Ana's party? do you bring something?)
Trae el coche que te lo necesito
(bring the car because I need it)
te llevaré el coche mañana
(I'll bring it tomorrow)
