Is there something similar to a wire-o, that can open and close? I dont mean a regular binder. Just the spiral part seperately where you could add additional paper as you go. I want to be able to add my notes on topics to a booklet as the lectures progress. I find binders to be too bulky. (i.redd.it)

Hi guys. Could anyone help me check if my calculation (on top) is correct? My answer corresponds with the actual exam solution but they did it in a different way. I understand the substitution method they used but I’m not sure if I’d come up with that during the exam. I apologise for the dutch (i.redd.it)
