9 6 EMPLOYMENT PSYCHOLOGY dividing, and pointing off decimals on a machine is an entirely different process from the process involved in the mental solution of identical arithmetical problems. In fact, a girl who knows nothing whatsoever of division can be taught how to divide on a machine in a comparatively short time. However, in spite of this fact, it is highly nec essary that a comptometrist have a fundamental knowl edge of arithmetic. A comptometrist who does not have this is far more likely to make errors and to overlook errors than one who does. The experiments conducted proved this conclusively. An operator who knows arith metic can frequently tell when her answer is wrong or absurd by a mere inspection. To be specific, the decimal point in a calculation done on a machine can be taken care of automatically by setting an index or pointer and then following certain definite rules as to which rows of keys to use. As long as these rules are followed, no mis takes will occur. However, when, by chance, the operator fails to follow these rules she may obtain a result as fol lows: 1468 x .00034 equals 4.9912. Now, the numerical answer here is correct, but the decimal point is in the wrong place, and unless the operator knows the arith metical rules regarding the use of decimals in addition to the rules governing the mechanical operation, she may see nothing wrong in the above answer. Frequent mis takes of this kind were found in the course of the experi ments on comptometrists. Such mistakes made in actual work are likely to be very costly. Even though mistakes in the long run tend to equalize themselves, the fact that most of them are not allowed to run long, but must sooner or later be corrected, usually with an amount of labor far more costly than the errors themselves, makes it very im portant to reduce such errors to a minimum.
