comment Compute shooting targets for the gunmen
Yes, I noticed, and I apologize. While most SEs are looking for a single, canonical, correct answer, PGP prefers games where multiple players can enter, trying to score highest/lowest points and get the winning score. PGP has a king-of-the-hill tag, for example. Another commentor thought there might already be a challenge like yours under that tag. I searched but couldn't find it. Not too late to edit yours.

I can't help but think that this would also make an excellent challenge on Programming Puzzles and Code Golf SE.

comment How do I explain the Königsberg Bridge problem to a child?
(As noted) Repeat demo for several other similar diagrams. Then ask if anyone can guess why you can draw some but not others.

comment Why do we not have to prove definitions?
A wise old professor of mine once put it this way: Definitions are the playing pieces; axioms are the rules of the game; theorems are results we can obtain by following the rules and using the playing pieces.

comment How to explain brackets to young students
+1 for being the only answer here to call this thing by its proper name: Associativity. "Fear of a name only increases fear of the thing it represents" - Dumbledore.

comment Quick and painless definition of the set of real numbers
Can you use a (fantasy-world ideal with no restrictions such as the width of a graphite molecule) pencil to draw a line x centimeters long? If yes, then x is a real number.

comment Taking Calculus in a few days and I still don't know how to factorize quadratics
First, you should be able to succeed in calculus even with some small gaps in your knowledge of algebra, so you need not be overly worried. Next, I assume you have have already spent many hours with speaking with your teacher, reading your textbook, doing your homework, possibly with friends or in a study group, looking up online resources, and maybe even trying your parents, all in an effort to learn this topic. Unfortunately, this community is not going to be able to add anything new to what you've already done.

comment Algebra: What allows us to do the same thing to both sides of an equation?
@symplectomorphic: I agree 100%. But if it gets a learner started and helps with the basics before moving on to more advanced topics, what's the harm?
