Detailed Solution

The difference 463-9 is 454.
As we know, the associative property for subtraction says that the subtraction can be done irrespective of the choice of a group of elements whose difference is to be calculated.
That is,

⇒ 463 − 9 ⇒ 463 − 10 − 1 ⇒ 463 − 10 + 1 ⇒ 463 + 1 − 10 ⇒ 464 − 10 ⇒ 454

Hence, we perform the required subtraction with the help of associative property.
Therefore, the required difference is 454.
