Σελίδα 73 - Algebraic operations are based upon definitions, and the following axioms : 1. If equal quantities be added to equal quantities, the sums will be equal. 2. If equal quantities be subtracted from equal quantities, the remainders will be equal. 3. If equal quantities be multiplied by equal quantities, the products will be equal. 4. If equal quantities be divided by equal quantities, the quotients will be equal. 5.
Σελίδα 148 - To reduce a mixed number to an improper fraction, Multiply the whole number by the denominator of the fraction, and to the product add the numerator; under this sum write the denominator.
Σελίδα 147 - Now .} of f- is a compound fraction, whose value is found by multiplying the numerators together for a new numerator, and the denominators for a new denominator.
Σελίδα 49 - Find the first figure in the root, by the table of powers, which subtract from the given number. 3. Bring down the first figure in the next point to the remainder, and call it the dividend. 4. Involve the root into the next inferior power to that which is given ; multiply it by the given power, and call it the divisor. 5. Find a quotient figure by common division, and annex it to the root ; then involve the whole root into the given power, and call that the subtrahend. 6.
Σελίδα 73 - If the same quantity, or equal quantities, be subtracted from equal quantities, the remainders will be equal. 3. If equal quantities be multiplied by the same quantity, or equal quantities, the products will be equal. 4. If equal quantities be divided by the same quantity, or equal quantities, the quotients will be equal. 5. If the same quantity be both added to and subtracted from another, the value of the latter will not be changed.
Σελίδα 132 - Up starts a hare before my two greyhounds. The dogs, being light of foot, did fairly run, Unto her fifteen rods, just twenty-one. The distance that she started up' before Was fourscore sixteen rods just, and no more.
Σελίδα 32 - Multiply the divisor by this quotient; subtract the product from the part of the dividend used, and to the remainder bring down the next figure of the dividend.
Σελίδα 157 - Reduce compound fractions to simple ones, and mixt numbers to improper fractions ; then multiply the numerators together for a new numerator, and the denominators for. a new denominator.
Σελίδα 43 - To be 100 feet from th' top to th' ground ; Against the wall a ladder stood upright, Of the same length the castle was in height : •A. waggish youngster did the ladder slide (The bottom of it) 10 feet from the side ; ' Now I would know how far the top did fall, By pulling out the ladder from the wall t A 6 ini nearly 26.
Σελίδα 103 - Quantities is the least involved, and let the Value of that Quantity be found in each Equation by the Rules already given), looking upon all the Rest as known : let the Values thus found be put equal to each other (for they are equal...
