A merge of modern technology and ancient methodology, Digital Abacus is the timeless calculator for all ages.
For many, it's simply nostalgia, but for children it becomes a learning tool. Children slide the beads and count, visualizing the numbers as they interact with the app. It's a good way to learn basic number concepts they will take with them through life.
Features
- Learn the lost art of the abacus with the help of a digital readout.
-Work with an interactive counting tool rather than simply punching in numbers and getting an answer.
