6.7 - 39.31 = ?

Understand the Problem

The question is asking to perform a subtraction operation between the numbers 6.7 and 39.31. We will calculate the result step by step.

Answer

The answer is $-32.61$.

Steps to Solve

Align the Numbers Write the numbers one under the other, aligning the decimal points:
```
  6.70
- 39.31
```
Subtract the Numbers Start subtracting from the rightmost column. If you need to borrow, do so:
- In the hundredths place, $0 - 1$ requires borrowing. Borrow 1 from the tenths place (turning $7$ into $6$), making it $10 - 1 = 9$.
- In the tenths place, $6 - 3 = 3$.
- In the units place, $6 - 9$ requires borrowing again (turning $6$ into $16$), so $16 - 9 = 7$. Finally, $3$ is now $2$, making it $2 - 3 = -1$ after borrowing.
Write the Result Combine the results of the subtraction to write the final answer:
- The result we computed was as follows: $-32.61$.

The result of the subtraction is $-32.61$.

More Information

When subtracting a larger number from a smaller number, the result will be negative. In this case, $39.31$ is larger than $6.7$, resulting in a negative outcome.

Tips

Forgetting to align the decimal points, which can lead to incorrect results.
Not borrowing correctly when subtracting, leading to calculation errors.
