title: displaying different data (info, numbers) into different tableview cells
body: <p>i have tableview cells, each cell when tapped brings on screen calculator (SECOND viewcontroller), and when something is calculated i get numbers. I want for each cell to remember each calculated number,  i know i must use delegate to pass that numbers into previous tableviewcontroller into cell, problem is that all cells will get first number calculated. And when i click back tableview cells will not remember sum – numbers. So what the “simple” best path to do that, somehow to store data so each cell can remember specific numbers when i click back and forward. Here’s the video where i got stuck.</p>
