I got all but one of the recall 2 questions wrong... but the answers don't make sense :( I have a hard time knowing whether I really got them wrong or whether this is just another kink in the system?

Hi Ari, most of the Desmos lessons have been used before. So, there shouldn't be many issues with them. I do apologize for the kinks we are working out with the main classroom.
For 3.1 Slide 2, you'll need to put the value of x given into the expression (1+x)(2+x)(3+x)(4-x). Remember that the parenthesis without anything between them means multiplication; i.e. (3)(5)=3*5=15.
For #1, x=1, so the expression would be (1+1)(2+1)(3+1)(4-1). Evaluating this you get:
=(2)(3)(4)(3)
=6•12
=72
Thanks so much for your help!! Guess I just needed that cleared up XD
