What is the result of subtracting 20 from 30?

To find the result of subtracting 20 from 30, you perform the operation 30 - 20. When you subtract a smaller number from a larger number, the result is the difference between the two values.

In this case, starting with 30 and removing 20 gives you 10. This is accurately reflected in the correct choice, which indicates the straightforward arithmetic involved. Understanding subtraction as the process of determining the difference is key, and here it clearly shows that 30 less 20 equals 10.

The other numbers do not represent the correct result of the subtraction operation, as they do not maintain the arithmetic relationship defined by the operation.
