So mr.maksymchuk spent a few minutes explaining to us that math is fake. It is something that we learn to build neurons and pathways in our brains or something so that we can solve problems when we're older. That's what i thought he was saying even if nobody really understood what he meant. He gave us an example saying that we will never have to find the slope of a purple line but we will wait in line to mexico and that's what learning about math is good for. I don't know, i didn't get it but anyways. After that, he taught us the steps of the substition method.
