Answer: Yes they have the same value
Both are equal to -15
Further Explanation:
If we ignore the negative, then 5*3 = 15 and 3*5 = 15. The order of multiplication doesn't matter.
The negative is then introduced to let us say
-5*3 = -15
-3*5 = -15
This makes the final result negative. The negative flips whatever the previous result was.
