Example 3: Addition using Expanded method
in words.
489 + 222=?
Solution: By expanding the numbers;
489 = 4 Hundreds + 8 Tens + 9 Ones
+ 222 = 2 Hundreds + 2 Tens + 2 Ones
Sum = 6 Hundreds + 10 Tens + 11 Ones
= 6Hundreds + 10 Tens + (1 ten) 1 one
= 6 Hundreds + 11 Tens + 1 one
= 6 Hundreds + (1 Hundred) 1 Ten + 1 One
= 7 Hundreds + 1 Ten + 1 One
= 711
Therefore, sum = 711
