Yes abacus still in used today, specially for visual impaired students. Eventhough the talking calculator did help for visual impaired students at Braille schools across the nation, but talking calculator do not let students understand the important of number placement value.

The abacus was invented by the ancient Chinese people and was used to perform mostly mathematical calculations. In Japan, even to this day, the abacus is still used for simple calculations. Many people consider the abacus the first "computer" or at least the first calculator.
The same as it has been used for thousands of years: doing calculations. An expert abacus operator can visualise numbers and do calculations (usually) faster than someone with an electronic calculator - using an abacus visualised in their head, a skilled operator can often do calculations faster than with a physical abacus. Abaci have the advantage that the batteries don't wear out (as there aren't any), which makes their use in places with limited supply of power preferable.
The earliest recorded calculating device is the abacus. Used as a simple computing device for performing arithmetic, the abacus most likely appeared first in Babylonia (now Iraq) over 5000 years ago.
Yes.

yes but not many people use it
Before electronics were invented, Mathematicians used abacus's.

There was evidence of the abacus going back as early as 2700 B.C. And it is still commonly used in certain countries and places like Japan, China, Russia, and the Middle East.
