This document contains code for multiple Visual Basic programs that perform tasks like calculating averages, factorials, sums of series, displaying shapes, and formatting text properties. The code includes event handler subroutines for buttons to run calculations or clear fields, and code to perform calculations, format outputs, and set properties.
