Pretty slick. Now, if I can just remember it when I need it.

HAHa  I am dyslexic so by the time I get focused on the other fractional dimension on the tape I will have already forgot completely what it was I was adding or subtracting.  This is a very difficult concept for normals to grasp. They think you  are just being stupid or lazy or something.

 I just use decimals.  Base ten is easier.  A very long time ago I managed to memorize the fractional equivalents from many gozillions of repetitions so when I see a fraction I think the decimal.

It's funny the way memory works.

Cliff,

Count me in the group that would like to have a base ten tape.
