Yep. The answer is A. I have done this test.
Here's what is wrong:
B. Is completely wrong because remember there are NEGATIVE tiles too. And in this equation there are more NEGATIVE tiles than positive.
C. Has the wrong product; It would be 20 NOT 8.
D. Has the wrong product; It would be 8. When subtracting NEGATIVE numbers, the answer will be NEGATIVE. Unless the number that you subtracted had a bigger sum than the 1st number, then, the answer would be POSITIVE. But in this question, it's MOST definitely NEGATIVE.
