Answer:
seis
Explanation:
*this isn't French, but I'll go with it.*
From my very limited Spanish knowledge, dos means 2 (it actually sounds like the French way to say 2) and cuatro means 4 (also sounds like French way to say 4!). 2+4 is 6, and 6 is seis.
If you are malade, you should go to the doctor.
I'm not doing good, because I am depressed.
