3. Calculators
The first calculators (known as arithmometers) could only perform 4 functions: addition, subtraction, multiplication, and division. Besides, the quality of the calculations depended not on the device but on the accuracy of the person who performed them.
The calculators of today are much simpler to use, more functional, and, most importantly, much more compact!
