When the year can be divided by 4 without a remainder, it is called leap year, in which February has 29 days. Note 6.—Although 13 months is not an exact year, it will be sufficiently accurate in the following questions to carry for that number. 25.

A certain note was on interest 2 y. 48 m. when a part of the note was paid. ' After the payment it was 2 y. 3 mo. 3 w.5 d. 20 h. 45 s, before the – note was taken up. How long from the time the note was given until it was taken up 3 Ans. 4 y. 3 mo. 3 we 5 d. 20 h. 48 m. 45 s. 29. The longitude of Philadelphia is 75° 9' west, and that of Rome, 12°29' east, and that of Moscow This measure is used in reckoning latitude and longitude; in computing the revolutions of the planets; and in measuring most other circles. Remark.-Every circle, whether large or small, is supposed to be divided into 360 degrees, consequently, a degree in a large circle, must be longer than one in a small circle; and the minutes and seconds must vary accordingly.

Ells are measures used in several countries of Europe for measuring cloth; but in the United States, the yard is used. Spirits, perry, cider, mead, vinegar, honey and oil are measured by this measure. 35.

Grain, fruit, seeds, roots, salt, sand, oysters, &c. are measured by this measure. When the sum of two or more numbers of different denominations, and one of the numbers represents a different quantity from either of the others is to be expressed, we find that sum by adding; but when several equal numbers of different denominations, are to be collected into one number, the operation is performed by multiplying. The only difference which exists between multiplying a compound and a simple number, is, that in multiplying a simple number, we always add 1 to the next left hand place for every 10; but in multiplying a compound number, we carry for different numbers from one denomination to another, but for 10, when multiplying one denomination, when that denomination contains more than one column of figures. But in both cases we increase the numbers to: wards the left, by the same general principle, for in both, we carry for a number in the place we are multiplying, which is equal to one in the next place. When the multiplier does not exceed 12. RULE.—Write the multiplier under the last denomination of the multiplicand. Multiply each denomination as in simple numbers, beginning with the least; observing to carry one to the product of the next higher denomination, for as many as it takes of |
