When I am rounded to the nearest ten I am one thousand. I am the same when read forward or backward. I can be two different numbers who am I

1001 or 999

999 or 1001

round to the place value of the underlined digit

To find the answer to this riddle, start by thinking about what it means to be rounded to the nearest ten. When a number is rounded to the nearest ten, the digit in the tens place becomes either the previous multiple of ten or the next multiple of ten, depending on whether the ones digit is closer to the previous multiple or the next multiple.

Since the number in this riddle is rounded to the nearest ten and it is equal to 1000, we can determine that the rounded number is either 990 or 1010.

Next, the riddle states that the number is the same when read forward or backward. This means that the number is a palindrome, which is a number that remains the same when its digits are reversed.

Considering this information, we can determine that the correct answer is 1010. When read backward, it is still 1010.

Therefore, the number that is rounded to the nearest ten and is the same when read forward or backward is 1010.
