The first mechanical counting device was invented by Blaise Pascal in 1642. It was primarily used as an adding machine. It could add and subtract two numbers.
The first modern-style electronic calculator was invented in the 1960s. The first counting device, an abacus, was invented in Egypt in about 2000 BCE. The mechanical calculator was developed in the 17th century.
The introduction of the 1st mechanical calculator was invented in Europe. This type of calculator production then spread world wide. The first ever was invented by Willhelm Schickard.
Because it was the first portable counting device - sort of the first 'pocket' calculator !
Most answers to that question on this site give the answer as Abacus.

The abacus is the original mechanical counting device. It was likely first used over five thousand years ago, and used beads to keep track of numbers.

A mechanical loom is a device which simplifies the process of manufacturing textiles. It was invented by Joseph Marie Jacquard and was first demonstrated in 1801.
who invented the first mechanical digital calculator
Abacus
The first reports of a mechanical dishwashing device are of an 1850 patent by Joel Houghton of a hand-powered device. Modern dishwashers though, come from an invention in 1886 by Josephine Cochrane.
The first mechanical calculator is attributed to Blaise Pascal, who invented the Pascaline in 1642. This device was designed to perform basic arithmetic operations like addition and subtraction. However, earlier counting devices, such as the abacus, have been used for centuries before Pascal's invention. Therefore, while Pascal is often credited with creating the first mechanical calculator, the concept of calculation has a much older history.
