To find the result of subtracting 19 from 30, you perform the simple arithmetic operation:

30 - 19.

When you take 19 away from 30, you can visualize this by starting at 30 and counting backwards by 19. To break it down:

1. Start at 30.

2. Subtract 10 to get to 20.

3. Then, subtract another 9 to get to 11.

Thus, the result of 30 - 19 is 11. This is why the response indicating 11 is correct. Additionally, understanding how subtraction works—by determining how much is remaining after taking away a quantity—is key in performing such calculations accurately.
