Inimitable CURTA

Aja!. This is the inimitable, the wonderful, the incredible, the small and powerful "CURTA". Don't be wrong, despite of its reduced size and lightness it equals in exactitude and power of calculation to desktop machines that weights 15 or 20 pounds. And it fits in the palm of your hand!.
Observe the upper ring, it is the movible carriage, the characteristic that distinguishes this device from a simple adding machine and enables it to perform the four operations in a fast, simple and infallible way.

Let's see a simple example: How many hours in a year?: introduce value 365, turn the crank 4 times for the units, move the carriage to the position of tens and turn the crank twice . The result appears instantly!. It seems magic, but it is science.
There is no error possibility because the factors and the result remain visible, so that you can verify them.
Ah! and it's Earth-friendly, no electrical consumption, no polluting batteries are involved in operation.

The metallic case, specially designed, protects the high precision mechanism, so you can carry your CURTA anywhere you need its high computing power.
