  • A number can be named in different ways and can be written in different ways’

  • When we expand a number, we stretch it out to show the value of each digit.
   
Example:  123 =               100 +20+3  
                  246 =              200 +40 +6
                 2459 = 2000 + 400 +50 +9
To see it our answer is correct, we add the expanded numbers.
Example: 123 = 100 +20 +3
+  1
