E^{3}value properties can be computed by expressions that refer to other
properties in the same model. The language to do this consists of two
parts, one to construct numerical expressions and one to construct
navigation paths.

To do value flow analysis, the editor transforms the navigation path
into an Excel cell reference and the resulting expression is evaluated in
Excel. Hence, any Excel formula can be used as an e^{3}value expression.
See https://www.excelfunctions.net/excel-operators.html for an
overview.

In this appendix we explain the syntax of the navigation language of
e^{3}value , using the diagram in figure C.1 as running example.
