Ah, rounding numbers can be a peaceful experience. If we take the number 430 and round it to the nearest 10, we see that it is closest to 430 itself. So, 430 rounded to the nearest 10 remains 430. Just a gentle adjustment, like adding a happy little tree to a painting.
To round 430 to the nearest 10, you look at the digit in the tens place, which is 3. Since 3 is less than 5, you would round down to the nearest 10. Therefore, 430 rounded to the nearest 10 is 430.
