Identify Numbers and Operation: Identify the numbers and the operation to be performed. We have the number 7 and we need to subtract 1 from it.
Perform Subtraction: Perform the subtraction operation. Subtract 1 from 7 to get the result. The calculation is 7−1=6.
Check for Errors: Check for any mathematical errors in the calculation. Since 7 is greater than 1, and we are subtracting a smaller number from a larger number, the result should be positive and the calculation should be correct.
