Talking about spreadsheet

Hey Friends! We have watched a TED conference about the inventor of the spreadsheet. His name is Dan Bricklin and he always had dreamt about a program to make calculations in an easier way. His dream came true thanks to the help of his friend Bob who worked in an attic of Arlington Massachusetts. From my point of view that was an incredible idea. In the conference he said that having a little failure in a calculation is frustrating and I do share this feeling.💻💻
