Mechanical calculators based upon equations that can be interpreted in terms of plane or spherical geometry are easily to construct and to operate. They mostly are precise enough for practical applications. The time of adjustment and calculation is very short, and therefore this kind of device will be welcome whenever time plays an important role.
