It does not contradict my assertion. I did not discuss multiplication. The answer is that it depends on how you multiply. You did not state how you multiplied but I am sure you used the * operator. Using the * operator, you will get 123. If you use product(a1), where a1 contains '123, you will get 0. Operators and functions do not work the same. ________________________________________ From: Denis Navas Vega [denis.na...@gmail.com] Sent: Monday, November 11, 2013 22:06 To: users@global.libreoffice.org Subject: [libreoffice-users] Re: CALC convert text to numbers El 2013-11-11 04:00 p.m., David Gast escribió: > Spreadsheets use the MVC (model view controller) paradigm.

A) Write just: 123 --> That's a number (just to compare). B) Write : '123 --> That's text. Sum(cell) is equal to cero. C) Multiply: In another cell write a formula that references '123 address and multiply by 1. You get a number!
