The expression is .
Line up the decimal points and draw a line below the numbers.
\First find the difference on the ones digit.
\Notice that it is not possible to subtract 3 from 9.
\So, 1 unit must be borrowed from tens column.
\The difference of the ones digit = 13 – 9 = 4
\Next find difference of the tens digit.
\Notice that it is not possible to subtract 3 from 5.
\So, 1 unit must be borrowed from hundreds column.
\The difference of the tens digit = 13 – 5 = 8
\Next find the difference of the hundreds digit.
\The difference of the hundreds digit = 6 – 2 = 4.
\The difference is 484.
