ESL Spoken English Sessions: Various ways to say "no"/express negation and yes/affirmation

This was also originally a tip I recorded for my students but I will share it here: how to express "no" or negation and "yes" or affirmation in other simple ways instead of just saying "no". I have also different ways of posing/asking certain simple questions politely, indirectly or any other way that is nice as an answer to a student's query.
