Because many people do not understand the differencebetween a manual calculation aid, a calculator, and an automatic computer.
A manual calculation aid is a manual device where the user needs to fully understand the calculation and how to manipulate the parts of the device to perform every step of the calculation. The user must perform every step of the calculation on the device himself by hand. An abacus is a manual calculation aid. A sliderule is also a manual calculation aid.
A calculator is a manual device where the user needs to understand the calculation he wants to perform but the device can perform the detailed steps itself. The user must request each step of the calculation from the device by hand.
A computer is an automatic device that once set up (programmed) will perform the calculation anytime it is needed, without any attention from the user and even if the user has no understanding of the problem at all (the designer of the program is the only one that had to understand the problem).
