Webb8 mars 2024 · Example 2: Let a = 4 and d = 3. Since 3 ̸ 4, the theorem says: ( − a) div d ≠ − ( a div d) ( − 4) div 3 ≠ − ( 4 div 3) − 2 ≠ − ( 1) − 2 ≠ − 1. So the second example works as well. These examples suggest why this theorem is true. It has to do with how the div operator works with negative numbers.
