Changing value and it’s compared
To create the greatest number : arrange the digits from big to small
From left to right.

following cards :
6 9 3 2
The greatest number: 9632 , The smallest number : 2369
Rounding rule:
-circle the digit to the right of the digit to be rounded
- I f it is 5 or greater, we add one to the left digit
- If it is 4 or less then we do nothing
- And we put zeros in all the digit before the one to which you want to round
