Abacus

Abacus is an educational calculation application developed by the Sugar Labs Community for Linux platforms. It provides a visual interface modeled after traditional counting frames to assist users with fundamental arithmetic calculations.

The application enables learners to manipulate virtual beads or input numeric values to perform basic mathematical operations, including addition, subtraction, multiplication, and division. The interactive representation helps clarify number relationships and place values.

Published under the GPL-3.0-or-later license, Abacus is designed primarily for elementary education environments. Its functionality is restricted to basic arithmetic and visual counting, omitting complex scientific functions.
