2.) \( \begin{array}{r}312.36 \\ -\quad 37.65 \\ \hline\end{array} \)

When you subtract \(37.65\) from \(312.36\), it's essential to align the decimal points to keep your numbers organized. Start from the right, where the smallest digits are, and work your way over. In this case, \(312.36 - 37.65\) equals \(274.71\). Always check your work by adding the result back to the subtracted number to see if you return to the original number! One common mistake while performing decimal subtraction is not keeping the decimal points aligned, especially with longer numbers. Always line up the decimal points vertically to avoid confusion. Additionally, remember to borrow when the top digit is smaller than the bottom digit; this is a crucial step in maintaining accuracy. Happy calculating!
