#### Answer

The numbers are subtracted in the same way as in the ten base. When a larger number is subtracted from a smaller number in the same column, then the value equal to the given base (base-5 in this case) is carried over from the adjacent column is carried over.

#### Work Step by Step

Also, take the numbers such that the sum of the numbers is bigger than the base.
\[\begin{align}
& \text{ 6 7 } \\
& \text{ 72} \\
& -\text{ 53} \\
& \text{ }\begin{matrix}
\text{ 1 4 } \\
\end{matrix} \\
\end{align}\]
The above calculation is done as:
For the last column:
Since 3 cannot be subtracted from 2, 5 from the adjacent column is carried over to 2, which makes it:
\[{{7}_{five}}-{{3}_{five}}={{4}_{ten}}=(4\times 1)={{4}_{five}}\]
For the first column:
\[{{6}_{five}}-{{5}_{five}}={{1}_{ten}}=(1\times 1)={{1}_{five}}\]
