Hi Jonas, I enjoyed watching your video about subtraction of polynomials. This is a really challenging part of the unit, so its a great idea to record what to do. A few suggestions to make things even better, the minus sign between the tiles is unnecessary as the colors of the tiles show the -/+. It would have been great to really emphasize that you flipped over the second expression because of the subtraction sign in front of the brackets. It happens so quickly that if another student watched this they might have missed the flipping of the tiles AND not understand why.
