She tears the note up and tosses the pieces into the wastepaper basket without a second thought. Then she goes at her work with a plunge, and soon becomes absorbed in its figures
The preoccupation with numbers throughout the play is interesting. Many of the characters' actions revolve around collecting capital: Crofts and Mrs. Warren justify their business by needing money, Rev. Gardner and Frank argue because Frank does not work or have his own money, Frank justifies marrying Vivie to Rev. Gardner by citing how much money she has, Mrs. Warren attempts to persuade Vivie to keep a relationship with her by providing her with money, etc. Throughout the play, numbers are thrown around in order to highlight the severity or extravagance of a particular person's situation. Furthermore, Vivie, who constantly speaks out against capitalistic motives, works with numbers; and, it is with numbers that Vivie finds refuge--after literally saying "goodbye" to everyone, she experiences "intense relief" and "becomes absorbed in its figures." It is with this image that the play concludes: Vivie, seemingly content, alone from everyone previously in her life, with numbers.
