Sam says 90 : (-9) = 10. Is he correct? Use the drop-down menus to explain your answer.

No.

Step-by-step explanation:

Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!

90 / 9 does equal 10, but 90 / - 9 equals - 10.

The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.

Thus, the correct answer should be - 10.
