Description
Mag World is an effort to develop fluency in logarithmetic, by using simplified notation for numbers that focuses on the magnitude. This develops a corresponding intuitive sense of scale–not just "bigger" or "smaller", but how much bigger, and how much smaller. And what are each of the levels of scale like?
