Question

Sum of the integers of predecessor and successor of -1 is

Answer 1

Hey!

This is the solution of your query.

FEW POINTS :-

Successor of an integer which is succeeding it means which is one more than the number.
Successor of A = A +1.

Predecessor of an integer is that number which succeeds it.
Predecessor of A = A -1

Now, 
Successor of -1 = -1 +1 = 0.
and predecessor of -1 = -1-1 = -2.

Now, their sum  = 0 + (-2)  = -2.

Hence, the sum of successor and predecessor of -1 is -2.

Hope it helps....

Answer 2

Hey!

Here is your answer.
 B4 solving, see these two points:-

Successor is that number which one more than the actual number.

Predecessor is that number which is 1 less than actual number.

So, 
Successor of -1
= -1 +1 = 0.
Predecessor of -1
= -1-1 = -2.

Sum of successor and predecessor 
= 0 + (-2)  = -2.

Hence, the sum of successor and predecessor of -1 is -2.
Hope you got it.......
