All right so what's going on here? I'm trying to depict that an algorithm basically it's a series of decision principles I guess and that you present a question to the algorithm and there are numbers of answers that it could be. Based on one answer, it'll ask another question and give feedback and then ask other questions and give feedback. Okay. Where have you heard about algorithms? Well I studied media, so I probably should have a more sophisticated explanation for what an algorithm is, but I don't think I've ever actually read what an algorithm does on like a step by step basis. Okay. Is this a question mark? Yeah that's a question mark, those are question marks. Okay, great. Thank you.
