In Simple Present Tense, in the affirmative form, if the subject is one of he/she/it, we add the relevant -s (-s or -es) to the end of the verb. If the subject is something different from the counted ones, we just use the first form of the verb (V1). In the negative form, we use "doesn't" as the auxiliary verb for the subjects he/she/it. If the subject is something different, we use "don't". The verbs are in the first form in both conditions. For the question form, if the subject is one of he/she/it, we use "Does" as the auxiliary verb. If not, we use "Do". The order is: Does/Do + subject + V1?
In Present Continuous Tense, in the affirmative form, if the subject is "I", we use "am". If the subject is one of he/she/it, we use "is". If the subject is one of you/we/they, we use "are". The verbs take the -ing in their ends. For the negative, just add "n't" right after the is/are. For "am", it is not true to say "amn't". We should use it like this: "am not". Remember that it is possible for both tenses to expand the known part: e.g. does not, is not, do not etc. This use is for emphasis. For the question form, the order is: Am/is/are + Subject + V-ing?
