Question

subtract.
79.64

• 58.18

Explanation:

Step1: Subtract the hundredths place

We subtract the digits in the hundredths place: \(4 - 8\). Since \(4<8\), we borrow 1 from the tenths place. The 6 in the tenths place becomes 5, and the 4 in the hundredths place becomes \(14\). Then \(14 - 8 = 6\).

Step2: Subtract the tenths place

Now we subtract the tenths place: \(5 - 1 = 4\).

Step3: Subtract the ones place

Subtract the ones place: \(9 - 8 = 1\).

Step4: Subtract the tens place

Subtract the tens place: \(7 - 5 = 2\).
Putting it all together, we have:
\[

$$\begin{align*} &\quad\ 79.64\\ &-\ 58.18\\ &\overline{\quad21.46} \end{align*}$$

\]

Answer:

\(21.46\)
