Final answer:
Affirmative and negative nosotros commands in Spanish are generally formed using the first-person plural of the present subjunctive. Examples of affirmative commands include 'Estudiemos' (Let's study) and 'Comamos' (Let's eat). Negative commands are formed by adding 'no' before the first-person plural present subjunctive verb.
Step-by-step explanation:
Both affirmative and negative nosotros comanda are generally formed using the 1st person plural of the present subjunctive. For example, let's take the verb 'estudiar' (to study). The first-person plural present subjunctive is 'estudiemos'. To form an affirmative command, we simply use the first-person plural present subjunctive verb, so it would be 'Estudiemos', which means 'Let's study'.
On the other hand, to form a negative nosotros command, we use the first-person plural present subjunctive verb but with a 'no' in front of it. So, for 'estudiar', the negative command would be 'No estudiemos', which means 'Let's not study'.
Other examples of affirmative commands with the first-person plural present subjunctive could be 'comamos' (let's eat), 'bailiemos' (let's dance), and 'hagamos' (let's do/make).
