PASCAL’S CALCULATING MACHINE WAS USEFUL IN

• A. addition and subtraction only ✓
• B.  division only
• C. multiplication and division only
• D. multiplication only

The answer to the question is: A. addition and subtraction only

Pascal’s calculating machine, also known as the Pascaline, was a mechanical calculator invented by French mathematician and philosopher Blaise Pascal in the 17th century. The Pascaline was an early example of a mechanical calculator and was designed to perform addition and subtraction.

The Pascaline was capable of performing addition and subtraction operations, making it useful for basic arithmetic calculations. It was not capable of performing multiplication or division operations.

The Pascaline consisted of a series of gears and wheels that could be used to input numbers and perform calculations. It was a significant advancement in the field of computing at the time, as it allowed for more efficient and accurate arithmetic calculations compared to manual methods.

Pascal’s calculating machine was useful in performing addition and subtraction operations, providing a valuable tool for mathematicians, scientists, and engineers who needed to perform repetitive calculations quickly and accurately.
