Rounding with Carrying to the Next Place

When the digit in the target place value is 9{9} and the digit to its right is 5{5} or greater, adding 1{1} produces 10{10}, which requires carrying 1{1} to the next higher place. For example, to round $103{,}978to the nearest hundred: the hundreds digit is{9}and the digit to its right is{7}. Since \7 \geq 5,add, add {1}toto{9},yielding, yielding {10}.Replace. Replace {9}withwith{0}andcarryand carry{1}tothethousandsplace,changingto the thousands place, changing{3}toto{4}. Replace the tens and ones digits with zeros. The result is $104{,}000.
