对列表视图或列表框中的一组数字执行数学运算 [英] Performing mathematical operations on a set of numbers in a listview or listbox

问题描述

嗨...

我正在为学校的项目工作创建一个n应用程序，在那里我需要创建一个大约六列的数据.第一列是日期.数据应该由我的应用程序的用户输入.

I am creating a n application for my project work in school where I need to create a data with figures of about six columns. first column is date. The data is supposed to be entered by the user of my application.

在此之后，用户必须按一个按钮来添加，减去，划分，绘制各个列中的所有图形.产生答案.就像Excel的工作原理一样.我似乎无法解决这个问题.

After which the user has to press a button to add, subtract, divide,ect all the figures in the various columns. To produce an answer. Just like how Excel works. I cant seem to get my head around it. 

有帮助吗?预先感谢
