Aligning and Writing Numbers: Align the decimal points and write the numbers one below the other.We need to subtract 0.107 from 2.23. To do this, we write the numbers vertically, ensuring the decimal points are aligned:\begin{align*}
&2.230 \
- &0.107
\end{align*}
Performing Subtraction: Perform the subtraction starting from the rightmost digit.We subtract each digit in the subtrahend (0.107) from the corresponding digit in the minuend (2.230), borrowing from the next left digit if necessary.\begin{array}{r}2.230 (\newline\)- 0.107 (\newline\)\hline2.123\end{array}We do not need to borrow in this case since each digit in the minuend is greater than or equal to the corresponding digit in the subtrahend.
