To think: Creer vs Pensar

[Dom]

I was wondering about how to use "creer" vs "pensar" so please tell me if I am correct based on these examples.
(Also if my Spanish is right, still learning)

Creer: I think that he is right. Yo creo eso el es correcto.

Pensar: I am thinking of what time to go. Yo pienso de que hora a ir.

Thanks a lot

You have figured out how to use these verbs, but they sometimes overlap.

Your Spanish is not quite right. Word-for-word translations will often not work.

creo = I believe (there's no need for the subject pronoun 'yo' in the present indicative tense, unless you're trying to emphasize)
que = that (conjunction) - 'eso' is a relative pronoun
él = he
tiene razón = is right (literally, "has reason")

pienso en = I'm thinking of
a que = at what
hora = time
irme = to go (literally, "I'm going" (leaving one location to go to another))

Alright thanks. Still trying to figure out how to make sentences properly in spanish. For "irme", is that to use if i'm only talking about myself? Could I use it if I was talking about a group of people or somebody else?

It only works for yourself. The pronoun on the end will change according to person and number. The infinitive and the possible reflexive pronouns appear below.
