- Thus, the sum of the two numbers is 579.ïNote that ç two numbers
- can be added with the number "456" on top and the answer is the same.
- The addition of two numbers can also be expressed as, 123 + 456ï=ï579,
- but you may prefer to add the numbers in a column as done above.
-
- Finally, when the number "0" is added to any other number, the number
- is unchanged.ï(ï5 + 0è=è5 )
