SIMPLE DIVISION teaches to find how many tiine one whole number is contained in another; and also wha: remains; and is a concise way of performing several sub) tractions. Four principal parts are to be noticed in Division : 1. The Dividend, or number given to be divided. 2. The Divisor, or number given to divide by. 3. The Quotient, or answer to the question, which showa how inany times the divisor is contained in the dividend. 4. The Remainder, which is always less than the divisor and of the same name with the Dividend. |
