That is why calculators were made.

The "original calculator" is called the abacus and was invented in 2nd century china. It was developed in order to assist with calculations and to improve overall speed. The thing is that the abacus was invented before written language was, and as such was used in place of what we would typically use, paper.
One of the improvements that has been made to the calculator since the invention of the device is that calculators are much smaller now. Another improvement is that many of them are solar powered.
The improvements were made to PATA to allow for the programs to load faster. The improvements are made to make navigation easier as well.
