Given the numerical expression:

(6.42)-(-3.2)

Solution:

Since the given numerical expression is separated by a minus sign, and we have a negative number that will be subtracted, we apply the rules of multiplication and division on the signs. Similar signs mean we will have a positive answer, and opposite signs mean we will have a negative answer, therefore - (-3.2) will become + 3.2.

= (6.42)-(-3.2)

= 6.42+3.2

= 9.62

Final answer:

9.62
