Question: A carpenter bought a piece of wood that was $86.08$ centimeters long. Then she sawed $6.977$ centimeters off the end. How long is the piece of wood now?
1. **State the problem:**
We need to find the length of the piece of wood after sawing off $6.977$ centimeters from the original length of $86.08$ centimeters.
2. **Formula used:**
The new length is given by subtracting the sawed length from the original length:
$$\text{New length} = \text{Original length} - \text{Sawed length}$$
3. **Substitute the values:**
$$\text{New length} = 86.08 - 6.977$$
4. **Perform the subtraction:**
$$86.08 - 6.977 = 86.080 - 6.977 = 79.103$$
5. **Final answer:**
The piece of wood is now $79.103$ centimeters long.
