Abstract
This paper establishes that (mod and integral) sum graph labeling for the friendship graph and also find (optimal, mod and integral) sum number for . Moreover an attempt has been made and also (mod and integral) sum numbers for the ladder graphs , for , the crown graphs for and for are determined in this paper.
