Pocket calculator
In recent years， pocket calculators have become almost as commonplace as watches.
A great variety of calculators are now available at reasonable prices.
I think the following points should be taken into consideration when you are buying a calculator. First there are a number of things the calculator can do .Next， there are calculators with a “memory” which allows you to store information and recall it when needed. Some expensive calculators have a choice of complex calculating routines which will be done automatically. Lastly some calculators can print the calculations while keeping a permanent record of them.
