Minor Expression Number

The Minor Expression number is based on the current (or short)
name; the name you now use to introduce yourself including your last
name.
The influence of the short name is minor in comparison to your full
name. Interestingly, the short name often compensates in some way
for numbers (and their related characteristics) that are missing or out
of balance in the full name.
For instance, a number missing in the full name may show up
prominently in the short name; or a number (or numbers) that
appears in excess in the full name can be compensated for in the short
name. If a name change takes place later in life through marriage or
for professional reasons, it adds or subtracts certain qualities. It can
also focus and intensify existing characteristics or talents that may be
latent.
