Most likely I haven't got it 100% correct especially with punctuation but that's the jist of it.
Verbs ending with er like comer in past tense usually end as you see you above unless they are irregular verbs (bangs head on table)
And for hablar or verbs ending in ar they follow a different trend.
Present/
Hablo,hablas,habla,hablamos,hablastais,
Hablan.
Past/ recent
Hablé,hablaste,habló,hablemos,hablastais,hablaron.
Imperfect/
Hablaba, hablabas, hablaba, hablábamos, hablabais, hablaban....
Future tenses are much simpler but hopefully I've been a little help.
There is a pattern see if you can spot it and apply it to verbs and change the tenses.
e, as, a, emos, eis, an.
