> By my meaning it's not very good policy. We all were learned > couple years that 12 is 12, not 18. Actually my sister has a degree as teacher for 5-12 y kids and one of the things she was trained in was to learn kids count and calculate in different radixes, like counting: 8, 9, bang, kwak, 1-0, 1-2, .... 1-8, 1-9, 1-bang, 1-kwak, 2-0 etc. Don't take anything for granted in the modern world!
