Both sums equal 4.الإجابة الصحيحة
Swapping the order of two addends leaves the sum unchanged.الإجابة الصحيحة
-6 + 10 equals -4, because the leading term is negative.
10 + (-6) is greater than -6 + 10.

الشرح

Each line describes the same pair of moves, six steps left and ten steps right, so both finish four steps above zero and neither arrangement has an advantage. Taking the sign of the leading term would make the two lines disagree even though the moves inside them are identical.
