My choice is D.
A) A = B
So A+B = 0 Suff
So for any combination can result summation to zero.
B) B = A
or, B+A = 0; Suff
Both are sufficient to get the value, hence D.
Please rectify me if I am wrong

i don't understand the explanation provided by gmatclub, so can someone explain to me in details? thanks! i am not good with absolute value, any study material recommended. thanks! What is the sum of integers A and B ? (1) A= B (2) B= A Both statements are saying the exact same thing: a+b=0, this to be true, both \(a\) and \(b\) must equal to zero. Absolute value is always nonnegative  \(some \ expression\geq{0}\), which means that absolute value is either zero or positive. We have that the sum of two absolute values, or the sum of two nonnegative values equals to zero: {nonnegative}+{nonnegative}=0, obviously both must be zero this equation to hold true. For theory check About Value chapter of Math Book created by Walker: mathabsolutevaluemodulus86462.htmlAbsolute value PS questions: search.php?search_id=tag&tag_id=58Absolute value DS questions: search.php?search_id=tag&tag_id=37Hard absolute value questions: inequalityandabsolutevaluequestionsfrommycollection86939.htmlHope it helps. P.S. For absolute value you can use  symbol.

1. A = B 2. B = A (1) A>=0 & B>=0 For A=B, is only possible if both are equal to 0. A+B=0 (2) Same logic as above. Sum is 0 Answer is (D)

What is the sum of integers A and B ?
1. /A/ = /B/ 2. /B/ = /A/
From 1 it implies /A/ + /B/ = 0 From 2 it implies /B/+/A/ = 0
So each one of the above is ok to answer the question

A module is always positive, therefore for the equations to be true both A and B = 0. In this case A+B=0.
Answer D

This question is some way A denotes the positive value of A. So how can that be equal to a negative number?

guys, there is an error on the question stem, please look how it is displayed for me:
What is the sum of integers \(b\) and \(b\) ?
\(a = b\) \(b = a\)

Answer is D, the scenarios in each case can only be true for 0. Each statement by itself is sufficient to derive this.

Find A+B
Modulus of any number is always +ve.
(1) A = B positive number is ve * a positive number.... only possible if numebrs are equal to 0 so 0=0 =>0 =0 . So basically here A and B both =0 . => A+B= 0 Sufficient
(2) B = A
Same description as above both A and B = 0. => A+B =0 sufficient
Answer: D
