If he knows add subtract multiply and divide then you can just introduce him to limits and L’Hopitals by trying to find out what happens if you divide 1 by zero. I’d like to apology because tape, scissors, paper and a pencil will get your miles and miles there; it can be very hands-on. I would think about p-adic numbers if they’re not too crazy. It’s a little bit of limits in a little bit of infinity. Sometimes games are useful. Chomp. How many possible games of checkers are there? Maybe how many possible games of tic-tac-toe are there. A good question. | |

| Oct 31, 2023 at 0:23 | comment | added | Rusty Core | Regarding multiplication and rectangles: why multiplication is represented with rectangles? Why not trapezoids or other shapes? | |

| Oct 30, 2023 at 14:23 | comment | added | Adam Rubinson | Same thing. "Summary of conclusion" and "reasoning" mean the same thing here. | |
| Oct 30, 2023 at 14:20 | comment | added | wizzwizz4 | @AdamRubinson It's not reasoning: it's the summary of the conclusion of what was probably a several-minute-long discussion. | |

| Oct 30, 2023 at 11:33 | comment | added | Adam Rubinson | "Why do we use a numbering system? (Because otherwise we'd need an infinite number of names)" That's not a good reason for using a numbering system. In fact, I'm not sure your reason has any explanatory power. The same goes for your second question: your reasoning for why it is the case is poor/lacking. | |

| Oct 30, 2023 at 8:52 | comment | added | philipxy | There are social, psychological & historical "reasons" "why" things in those realms have come about but a proof is not "why" something is a consequence, there is no such "why", only "demonstrations that" something is so. The only reasonable "why" a theorem is true is always the same--it is a consequence of assumptions/givens. | |

| Oct 29, 2023 at 10:21 | comment | added | David Raveh | How about polygons, polyhedra, etc.? My algebra professor brought in an icosahedron, and I managed to make my own out of magnetiles. You can build up from tetrahedron, to cube, octahedron,... Specifically, the question to pose is: what regular polyhedra can be made? | |
