I assume your teacher explained WHY that answer was incorrect?    

 

4 – 7 = –3      You had the "three" part right, but it's a negative three.   

 

Think about if you had 4 dollars, and bought something that cost 7.

 

You wouldn't have 3 dollars left in your pocket, you would still owe 3.  

 

In bookkeeping, they call that a negative balance.
