First Lesson in French

Salut = Hello
Bonjour = Good evening
ça va? or Comment tu vas ? = how are you? 
Je vais bien = I'm fine 
ca va = I'm fine
Je vais bien
Je = I
vais = am (vais is the first person conjugated form of the verb aller, which means "to go". So... Je vais, tu vas, Il/elle va, vous allez, nous allons, ils/elles vont.  "I am" would be Je suis, but you'll get into that later I'm sure :) Bonne chance!
bien = fine
et toi? = and you?
Au revoir = bye
