The Calculation

The given calculation is:

320 - 60 = ?

Step 1: Understanding the Calculation

To correct the calculation, we need to understand the concept of subtraction. Subtraction is a mathematical operation that involves finding the difference between two numbers. In this case, we need to find the difference between 320 and 60.

Step 2: Performing the Calculation

To perform the calculation, we need to subtract 60 from 320. We can do this by counting down from 320 by 60s.

320 - 60 = 260

Step 3: Verifying the Calculation

To verify the calculation, we can use a calculator or a computer program to perform the calculation. We can also use a mental math strategy, such as counting down from 320 by 60s.

Conclusion

In conclusion, the correct calculation is:

320 - 60 = 260
