 Abacus is a lightweight scratch pad for making quick calculations. It is programatic by nature and employs a simple custom scripting language designed around calculating. The scripting lanugage is fully features and supports functions, closures, variable assignment, dataframes, sereis, primitive data types, arrays, maps, etc.
 
+Abacus is similar to a very lightweight version of Jupyter, runs as a single binary, and using only a dozen megs of ram.
