УелЯдб 213 - 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.
УелЯдб 225 - Divide the difference of the extremes by the number of terms, less 1, and the quotient will be the common difference.
УелЯдб 208 - The head of a fish is 7 inches long, the tail is as long as the head and |- of the body, and the body is as long as the head and tail ; what is the length of the fish ? 9.

УелЯдб 215 - In any right-angled triangle, the square which is described on the side subtending the right angle is equal to the sum of the squares described upon the sides which contain the right angle.
УелЯдб 228 - Multiply the sum of the extremes by half the number of terms, and the product will be the required sum.
УелЯдб 226 - Divide the difference of the extremes by the common difference, and the quotient, increased by 1 , will be the answer.
УелЯдб 213 - ... a quotient figure in Division. Subtract the square thus found from the said period, and to the remainder annex the two figures of the next following period for a dividend. Double the root above mentioned for a divisor, and find how often it is contained in the said dividend, exclusive of its right-hand figure ; and set that quotient figure both in the quotient and divisor.
УелЯдб 126 - If A could do a piece of work in 10 days, B in 12 days, and C in 15 days, in what time could A and B together do it 1 In what time the three together do it 1 Am.
