Today, we'll talk about section 1.4 from our textbook on first order, linear equations. This is mostly symbolic manipulation so we're going to see how board work goes via Zoom!

Homework
There is a 10 point MyOpenMath HW due on Wednesday evening.

Quiz 1
We have a quiz during the last part of this week. You'll take this via MyOpenMath (I think) but it will not be anything like the HWs to this point. You'll get the problems (sometime after class on Wednesday), you will write out your solutions and then upload an image of your write up. Note that the quiz will close 1 hour after you start.To study for the quiz, you should do the three problems on our forum whose titles are not so cryptically prefixed "Quiz prep".
