Changing value and it’s compared

To create the greatest number : arrange the digits from big to small

From left to right.

Ex : Write the greatest and smallest number that can be Formed using all of the
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
