2. difference engine
3. tabulating machine
4. Leibniz's calculator

Answer 1

Answer:

1. blaise pascaline
2. Charles Babbage

Answer 2

The inventions of inventors:

1. Blaise Pascal was the inventor of Pascaline.

• The earliest calculator or adding machine that was made in any quantity and really utilized was the Pascaline, also known as the arithmetic machine.
• Between 1642 and 1644, the French mathematician and philosopher Blaise Pascal created and constructed the Pascaline.

2. Charles Babbage developed a different engine.

• An automatic mechanical calculator called a difference engine is used to tabulate polynomial functions.
• It was initially developed by Charles Babbage in the 1820s.

3. Engineer Herman Hollerith devised the tabulating device.

• An electromechanical device called a tabulating machine was created to help summarise data on punched cards.
• The device was created by Herman Hollerith to aid in the data processing for the 1890 U.S. Census.

4. Gottfried Wilhelm Leibniz was the inventor of the Leibniz calculator.

• The Step Reckoner was a calculator created by German mathematician-philosopher Gottfried Wilhelm von Leibniz in 1671. It was first constructed in 1673.
• Pascal's theories were developed by The Step Reckoner, who multiplied by repetitive addition and shifting.
