Explanation
Answer: D - You need to remember what happens when you multiply positives (+) and negative (-) numbers. First, simplify the two expressions -3-(-10) and -10-(-3) separately.
-3-(-10) = -3 +10 =+7
-10-(-3) = -10 +3 = -7
The catch in the problem id to calculate the difference between the two expressions
+7-(-7) =+7 +7 = +14

Key takeaway: Remember four simple rules what happens when you multiply positives (+) and negative (-) numbers.
Pos x pos = pos 2x3 = 6
Neg x neg = pos -2 x -3 = 6
Pos x neg = neg 2 x -3 = -6
Neg x pos = neg -2 x 3= -6
