An abacus could be considered an early ancestor to the calculator. It was made of wood and had wooden beads that slid on wires and were used to calculate arithmetic problems.
They used Roman numerals and an abacus counting device
Thailand vegetable vendors use abacus, nowadays abacus is gaining popularity in India, US and taught by many schools
Around 2500BC the first Abacus appeared in Sumaria. It arrived in Persia about 600BC. The Greek Abacus is recorded to have been in use about 500BC
With an abacus.
yes
They used Roman numerals and an abacus counting device
well here is the answer ! :)Some people use the abacus to solve some mathematical calculations
One of the advantages of the abacus is that it is easy to use. Another is that it does not require electricity to work. You can use it no matter where you are.

Oh, dude, it's "Gone are the days." Unless you're a time traveler reminiscing about days that have already passed, then I guess you could say "Gone were the days." But, like, let's stick with the present tense for now, okay?
An abacus is used as a tool to train children how to perform complex mathematical operations quickly and efficiently. One of the advantages of an abacus is that it gives a color coded physical representation of a number system. This allows a student proficient with an abacus to eventually start performing mathematical operations in his/her head as they can visualize how the abacus would look if they were to perform the operation physically. The abacus has another positive use as it is a good teaching tool to help blind students learn math.It is significant because it was the precursor to the modern calculator. It is a portable device that can be carried on person to perform mathematical operations without the need for a writing instrument or paper.Source: http://en.wikipedia.org/wiki/Abacus
