Addition and Subtraction 1. Addition and Subtraction: Determine the missing fractions and the sum or difference of the fractions for each pair of bars. For addition, use Fraction Bars to determine the sun by comparing the addend bars to a third sum bar as shown in the Sum Example below. Fo subtraction, use a third Fraction Bar to determine the difference by drawing two vertica lines on the minuend and subtrahend bars to indicate the difference on the difference bar a illustrated in the Difference Example below. Sum Example: Two addend bars 12 Sum bars 12 Difference Example: Minuend bar Subtrahend bar Difference bar 6. *a. b. 3
