Σελίδα 42 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
Σελίδα 39 - A circle is a plane figure bounded by a curved line, every point of which is equally distant from a point within called the center.

Σελίδα 14 - Place the numbers to be added so that the decimal points will be directly under each other. Add as in whole numbers, and place the decimal point in the sum directly under the decimal points above.
Σελίδα 7 - To reduce a mixed number to an improper fraction, — RULE : Multiply the whole number by the denominator of the fraction, to the product add the numerator, and write the result over the denominator.
Σελίδα 32 - ... and to the remainder bring down the next period for a dividend. 3. Place the double of the root already found, on the left hand of the dividend for a divisor. 4. Seek how often the divisor is contained...
Σελίδα 32 - Multiply the divisor, thus augmented, by the last figure of the root, and subtract the product from the dividend, and to the remainder bring down the next period for a new dividend.
Σελίδα 211 - ... estimates are usually too small and cause delay through an effort to correct the fire by making timid and insufficient changes in the range. Attention should rather be concentrated on deciding, from careful observation of each shot, upon the sense of a number of shots fired with the same range and site, and on quickly inclosing the target with fire which is surely short and fire which is surely over. By narrowing the bracket thus determined effective adjustment may be secured.
Σελίδα 212 - If the target is indistinct and of about the same color as the smoke, it may be less visible against the smoke as a background. A burst beyond the target may, for this reason, sometimes seem to obscure the target, and hence be judged short, when it is in reality over. On the other hand, some targets become very much more visible if projected against a smoke background.
Σελίδα 32 - TRUE DIVISOR. Multiply the true divisor by the last root figure, subtract the product from the dividend, and to the remainder annex the next period for a dividend.
