In French, you use the PASSÉ  

COMPOSÉ to say that you did something  

or have done something in the past.


Example -  English:  I ate.  French:  I have eaten.


There are two parts to the passé composé. 


Think of it like a math problem:  A + B = P.C.


A is your helping verb

B is your past participle

P.C. is the Passe Compose!
