A. 
  No, it is not reasonable because when you add two numbers you get a number greater than either of the two numbers. The answer is +10.   
   

 
 

  

  B. 
 
No, it is not reasonable because you subtract the smaller number from the larger number to get +2.

Yes, it is reasonable because if you start at +4, you will move 6 spaces to the left to get –2.
