Why Did The Treaty Of Versailles Fail ? Many historians claim that the Treaty of Versailles was a failure because it ultimately led to the rise of Adolf Hitler, Second World War and the Holocaust. However, the big question is why did the Treaty of Versailles fail.
An abacus is a counting device that uses beads on a table or string that represent numbers.bacus is not like the modern electronic calculators that perform all of the functions of their own and then present the result in an electronic form on their screens. It is rather a tool that helps in counting the numbers with the help of reference in its beads.
The abacus is a device, usually of wood (plastic, in recent times), having a frame that holds rods with freely-sliding beads mounted on them. Both the abacus and the counting board are mechanical aids used for counting; they are not calculators in the sense we use the word today. The person operating the abacus performs calculations in their head and uses the abacus as a physical aid to keep track of the sums, the carrys, etc.
