Calc is a spreadsheet for everyone from LibreOffice -- the most excellent free alternative to Microsoft Excel. This collection explains the use of 14 basic Calc Formulas from SUM to VLOOKUP divided into eight parts. Now you can easily learn and practice by reading them one by one via links below. Happy learning!

This tutorial is based upon the ideas of **14 Microsoft Excel Formulas/Functions Mostly Used in Works** (in Indonesian) by Jendela Tutorial. By this, we want also to show that Calc's functions are the same as and compatible with Excel's counterparts so it is possible for one to work with Calc only without relying to Excel.
