Traditional Way: Every calculated cell holds a formula written in
algebraic notation. To reference values, the row and column
intersection is used as the name of the value in the cell. You cannot
see the values calculated and the formulae at the same time. Shortcuts
usually exist to repeat, adjust, and enter a formula across a number of
T/Maker Way: There are separate cells for data and calculation trails.
Trails are written as an ordered series of operators. Values can
be referenced in a number of ways including simply placing an operator
in the cell adjacent to them. Trails can be reused by clicking a
special cursor on another cell where the trail is to be restarted with
step 1. Also, trails can calculate a number of values, not just one.
