One thing to keep in mind is that certain problems are very hard if not impossible with the wrong tool/strategy. A child in elementary school can do long division, but good luck doing that on an abacus (and doing it in your head doesn't count). Since SE has chosen the wrong architecture for the game, solving this problem is basically like trying to do division with an abacus, so I do understand it's hard, but it's also not my problem they chose to use an abacus when everyone else uses paper and pencil.
