The Chinese around 3000 BC invented the Abacus was the first calculating machine.
The French Joseph Marie Jacquard invented the first programmable machine with his Jacquard Loom in 1801. This used punched board to program weaving to create complex patterns.
Charles Babbage an Englishman and Cambridge Graduate, designed a mechanical calculating machine starting in 1812 for the express purpose of calculating logarithm tables for the British Navy. These mathematical tables were used in navigation by sextant. Babbage had noted that the human calculated tables frequently made mistakes and it was the elimination of these which he sought to eradicate.
Babbage completed a number of what he called Analytical and difference engines, but never completed them. The Admiralty who were sponsoring the equipment pulled funding on him a number of occasions which caused him financial difficulties.
Even though the machines were never completed, these are considered the first ever proper computers and our modern computers great-great-grand daddy. Had they been built in Babbage's time, they would have been a revolution in mathematics.
Recently the British Science museum in Exhibition Road South Kensington, built a copy of the number 2 Difference Engine, which was one of Babbage's most complex designs. It worked perfectly without modification and was accurate to six decimals.

Blaise Pascal invented the ancestor of the calculator.
The adding machine was invented by a nineteen-year-old French boy named Blaise Pascal way back in the year 1642. Called the pascaline, it was the first mechanical calculator that used gears. He invented it to help his father calculate taxes.A different machine was invented by William Seward Burroughs in 1885.
Abacus was the first calculating device invented by the Chinese.

John Napier's calculating machine invention is called "Napier's Bones."
We can say that it is China because they are the one who invented the first calculating machine, Abacus. Next is the Americans because Bill Gates Invented the famous OS, Windows.
