All command forms

Write the correct Spanish command for each verb.
NOTES:Usted and Ustedes form (affirmative and negative) – Except for the *affirmative tú form, the stem forms of the commands are derived from the yo form of the present tense (drop the “o” ending of the yo form). It is very important to remember to use the yo form, specially in those verbs where only the yo form is irregular.
