```Formula simplify for Solve

PB2=(A[]*D)+(A[]*B[]+A[]*D)+(A[]*B[]+A[]*B[]+A[]*
D)+(A[]*B[]+A[]*B[]+A[]*B[]+A[]*D)+(A[]*B[]+A[
]*B[]+A[]*B[]+A[]*B[]+A[]*D)

Hi there,

Please look at the above math statement. I want to incorporate very long
statements into long formulas & then solve for  D  - is there anyway of
abbreviating the above statement to a simple letter(s) like PB2 & then be
able to still solve for  D? I am sure you can - please show me how with
Mathematia example.

BTW - I am using version 5.1.0.0 on a PC

Many thanks for your attention.
Mr.Lea Rebanks.
