Answer:
-2
Explanation:
Since the operation in this expression is all division, you can just divide from left to right, starting with 100 ÷ (-10).
100÷(-10) is basically asking what multiplied by -10 equals 100. Since a negative number times a negative equals a positive, we know that we need to multiply -10 by a negative number in order to get 100. If we just divide 100 by positive 10, we get 10 (because 10 × 10 = 100).
Since 10 × 10 = 100, then -10 times -10 equals positive 100. Therefore, the answer to the first part of the expression is -10.
Now we move on to the second part of the expression. We already got 100 ÷ (-10) = -10, so now we divide -10 by 5. This is now asking what number multiplied by 5 gives -10. You can only get a negative number if you multiply a positive and a negative number, so we know the answer is negative (since 5 is positive). If we divide positive 10 by 5, we get 2 (because 5 times 2 is 10).
This is how we get our final answer, -2, because we know that -2 × 5 = -10 because 2 × 5 = 10.
