(Author of Mag World here) I'm here to attest that it's worked for me! I see now that I had a fractured collections of number lines in my head (thousands, millionths, billions, and of course all the various units). Since using mag notation and integrating it into my thinking, it has absolutely helped create a grounded "magnitude line" in my head. So I'm not proposing this idly. Notation is a tool of thought (as per Ken Iverson), and using mag notation consistently, turned the advanced method of "logarithms" into a basic perspective of magnitude for me.

Maybe give it a few weeks or months and see if it gets easier for you too.
