DIVISION OF SIMPLE NUMBERS. 22. DIVISION teaches the method of finding how many times one number is contained in another. The number to be divided is called the dividend. The number of times which the dividend contains the divisor is called the quotient. Besides these three parts there is sometimes a remainder, which is of the same name as the dividend, since it is a part of it. The sign usually employed to indicate division is . Thus, 12 = 3, denotes that 12 is to be divided by 3. By using this sign we may form the following 23. Division may also be represented by placing the Jivisor under the dividend, with a short horizontal line be (ween them ; thus, le denotes that 10 is to be divided by 2. In the same way we have =12-2; 4=13-3; 4=17-5; b=53-7. This method is employed, when in division there is a remainder, to express accurately the value of the quocient. What does division teach? What is the number to be divided called? What is the number by which we divide called? What is the number of mes which the dividend contains the divisor called ? There is sometimes another part, what is it? of what name is the remainder? What is the symbol of division ? By what other method is division denoted ? When the divisor consists of only one figure, we proceed as follows: Divide 973 by 7. Having placed the divisor at the 1 OPERATION. left of the dividend, keeping them 7)973 separate by means of a curved line, we draw a straight horizontal line 1 139 quotienta underneath. |
