Multiplication Tables
Not sure this is the right place. But been rediscovering some prime proofs by accident. And it got me thinking about multiplication tabkes and complimentary tables are the "easy ones" I left school when they were phasing out the importance of 11 and 12 tables. Just needed to go to 10.
Maybe other peoples brains work differently but why don't we just focus on the prime tables. Here is a table I whipped up
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

| 2 | 4 | 6 | 10 | 14 | 22 | 26 | 34 | 38 | 46 | 58 |
