No, you can't teach it anything, and it will tell you so--it cannot integrate knowledge you try to give it into its responses (remembering the context of previous queries is a very different thing). And even if it could, "adding/saying some basic algebra inputs" would be of no help at all because it has no understanding of what the words or symbols in your text mean ... the knowledge that it appears to have is a statistical distillation of a vast textual database scraped from knowledge sources.
