Review of Introductory Mathematics FOUR BASIC ARITHMETIC OPERATIONSDividingWholeNumbersDivision is the process of determining how many times one number is contained in anothernumber. When numbers are divided, the result is the quotient and a remainder. The remainderis what remains after division. The number divided by another number is called the dividend;the number divided into the dividend is called the divisor. Division is indicated by any of thefollowing:a division sign (÷)a division sign ( )a horizontal line with the dividend above the line and the divisor below the line##a slanting line a/b meaning a divided by bThus, the relationship between the dividend, divisor, and quotient is as shown below:37 Dividend÷ 4 Divisor9Quotient1 RemainderUnlike multiplication, the division process is neither associative nor commutative. Thecommutative law for multiplication permitted reversing the order of the factors without changingthe product. Indivisionthedividendanddivisorcannotbereversed.Using the equation form:a ÷ b =/ b ÷ a(1-6)For example, the quotient of 18 ÷ 6 is not the same as the quotient of 6 ÷ 18. 18 divided by 6equals 3; 6 divided by 18 equals 0.33.Rev. 0 Page 13 MA-01
