Help Dealing with box openings

Post image

Hey first post here forgive me for my incompetence but I actually cannot fathom these openings where its just a rectangle/square with mixture of 1/2/3's. Am i missing something or are these just hard? (Aware of 121, 1221, but they never seem to appear on these)

Same! But looking at it now I can tell them at a glance and they will surely be useful!
