An algorithm, drawn by a 71-year-old female financial analyst with a background in math studies in the US.

Just one other drawing, I want to ask you, which is can you draw how an algorithm works? I'm going to keep this on in case you want to narrate it, because it might help to say what you're drawing. I think of an algorithm as a decision tree. Okay. Can you draw that? So you have a question and there's two answers. Depending on what this is, then you might go over here or you might go over here and this might go up here. Then it might go over there and then somewhere down here you get an answer. Okay. Where have you heard of the term algorithm? Oh, when I was in school. For what topic? I was a math major. Okay. Okay.
