Question: Subtract: $6.2 - 2.956$
1. **State the problem:** We need to subtract $2.956$ from $6.2$.
2. **Align the decimals:** Write the numbers with decimal points aligned:
$$\begin{array}{r}
6.200 \\
-2.956 \\
\hline
\end{array}$$
3. **Subtract starting from the right:**
- Subtract thousandths: $0 - 6$ is not possible, so borrow $1$ from hundredths.
- After borrowing, hundredths become $9$ and thousandths become $10$.
- $10 - 6 = 4$
- Hundredths: $9 - 5 = 4$
- Tenths: $1 - 9$ not possible, borrow $1$ from units.
- Units become $5$, tenths become $11$.
- $11 - 9 = 2$
- Units: $5 - 2 = 3$
4. **Write the result:**
$$\begin{array}{r}
6.200 \\
-2.956 \\
\hline
3.244 \\
\end{array}$$
5. **Final answer:**
$$6.2 - 2.956 = 3.244$$
This means when you subtract $2.956$ from $6.2$, the result is $3.244$.
