This answer to your other question will answer this as well.

A formula =D4+D6 when parsed via FormulaParser gives

org.apache.poi.hssf.record.formula.RefPtg [D4]
org.apache.poi.hssf.record.formula.RefPtg [D6]
class org.apache.poi.hssf.record.formula.AddPtg

RefPtg points to the cell reference D4, and + is AddPtg

Note POI uses the format of Reverse Polish Notation i.e. it puts which puts the operator in the post-fix position.

In Reverse Polish notation the operators follow their operands; for instance, to add three and four, one would write "3 4 +" rather than "3 + 4".
