Explanation Definition used: Subtraction: The difference a − b is the number c for which a = b + c . To subtract two real numbers, add the opposite of the number being subtracted. Calculation: The given expression is − 1 2 − ( − 3 4 ) . By subtraction rule, it is clear that − a − ( − b ) = − a + b . That is, − 1 2 − ( − 3 4 ) = − 1 2 + 3 4
