after verbs denoting motion; the second supine, that in u, is used after certain adjectives. Remark: The supines are supposed to have been nouns of the fourth declension, that in um, a noun in the accusative case; that in u, a noun in the dative case (u for ui). LATIN-ENGLISH. Parentes mei in urbem migraverunt habitatum; exercitus hostilis adventavit agros nostros devastatum; uva immatura est acerba gustatu; aerumnae sunt durae toleratu; sitis difficillima est toleratu; pira sunt dulcia gustatu; luscinia cantans animos nostros delectat; hostes adventant expugnaturi urbem; non est dubitandum de immortalitate animarum; obtemperandum est praeceptis virtutis. ENGLISH-LATIN. The soldiers approach to deliver (supine in um) the king; the hos fle army approaches to capture the city; ripe grapes are sweet to the taste (supine in u), unripe grapes are difficult to be endured; they come to seize (fut. perf. act. of occupo) the fields; birds by singing (gerund) delight the mind; we must fight bravely for our native land (patria), the soldiers have approached to fight for their homes and their wives. The factors which, being multiplied together, produce a composite number, are sometimes called the component parts of the number. The process of finding the factors of which a given number is composed, is called resolving the number into factors. EXERCISES. 1. Resolve 9, 10, 14, 22, into their factors. 2. What are the factors of 35, 54, 56, 63? 3. What are the factors of 45, 72, 64, 81, 96? Some numbers may be resolved into more than two factors; and also into different sets of factors. Thus, 12 2x2x3; also 124x3=6×2. CASE I.-When the multiplier is a composite number. EXAMPLE 1.-What will 27 bureaus cost, at 31 crowns apiece? Analysis. Since 27 is three times as much as 9; that is, 27= 9X3, it is manifest that 27 bureaus will cost three times as much as 9 bureaus. factor, and so on till you have multiplied by all the factors. The last product will be the answer required. The factors into which a number may be resolved, must not e confounded with the parts into which it may be separated. Ta former have reference to multiplication, the latter to addition: that is, factors must be multiplied together, but parts must be added together to produce the given number. Thus, 56 may b resolved into two factors, 8 and 7; it may be separated into in parts, 5 tens or 50, and 6. Now, 8x7=56, and 50+6=56. EXERCISES. LESSONS IN ARITHMETIC.-No. XV. CONTRACTIONS IN MULTIPLICATION. ALTHOUGH the general rules previously given be adequate to the solution of all examples that occur in multiplication, yet in many Instances, by the exercise of judgment in applying the preceding principles, the operation may be very much abridged. DEFINITION.-Any number which may be produced by multiplying two or more numbers together, is called a Composite Number. Thus, 4, 15, 21, are composite numbers; for 4-2X2; 15=15000, and is the same as 15 X 1000, &c. 5X3; 21=7x3. Operation. Explanation. 9 Having resolved 27 into the factors 9 and 3, we find the cost Crowns 279 cost of 9 bureaus. of 9 bureaus, then multiplying that by 3, we have the cost of 27 bureaus. CASE II. When the multiplier is 1 with ciphers annered to It is a fundamental principle of notation, that each removal f figure one place towards the left, increases its value ten times; sequently, annexing a cipher to a number will increase its vale times, or multiply it by 10; annexing two ciphers will increase ciphers will increase it a thousand times, or multiply it by value a hundred times, or multiply it by 100; annexing &c. Thus, 15 with a cipher annexed, becomes 150, and s is the same as 15X100; 15 with three ciphers annexed, berant same as 15x10; 15 with two ciphers annexed, becomes 1500, 4. What are the different factors and sets of factors of 8, 16, 18, 20, 24? 5. What are the different factors and sets of factors of 27, 32, 36, 40, 48? We have seen that the product of any two numbers is the same, whichever factor is taken for the multiplier, and that the product of any three or more factors will be the same, in whatever order they are multiplied. For, the product of two factors may be considered as one number, and this may be taken either for the multiCASE III.-When the multiplier has ciphers on the right a plicand, or the multiplier.
