When I try to round up 3898 to 4000 I am coming up with 2,102? What am I doing incorrectly?

3898 —-> 4000 – = TOTAL

3 + 4 + 2 = 9

8 + 0 + 1 = 9

9 + 0 + 0 = 9

8 + 0 + 2 = 10

December 27, 2019 at 5:20 pm #8897You don’t always have to make all numbers add up to 9.

The number of digits the rounded-up value will have will depend on how much you round up to.

If you round up 3898 to 10,000 you would have rounded up by 6102 which has 4 digits.

If you round up 3898 to 4,000 you would have rounded up by 102 which has 3 digits.

If you round up 3898 to 3,900 you would have rounded up by 02 which has 2 digits.So in this scenario, you shouldn’t do the addition of 3 + 4 + 2 = 9.

Let me know if this clarifies.

When you round up 3898 to 4000 you will have to add a 3 digit number to 3898 to get 4000. So you don’t have to add the 3 + 4 + 2 to get 9.

The amount you round up will have one digit lesser than the original numbers.

Both 3898 and 4000 are 4 digit numbers so the amount you have to round up has to be a 3 digit number which is 102.
