Note that in the first step we are dividing a positive number by a negative number:
Therefore, we the exercise is:
Now we are dividing a negative number by a negative number, that is:
Therefore, the final exercise will look like this:
Since we have a positive number, it is greater than zero.
Therefore, the answer is:
<
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
Signs determine the final result! When dividing numbers with different signs, you get negative results. When dividing numbers with the same signs, you get positive results. This affects whether your answer is greater or less than zero.
Use this simple pattern: Same signs = Positive result, Different signs = Negative result. So (+)÷(-) = negative, while (-)÷(-) = positive!
No! You only need to track the signs through each operation. Since we're comparing to zero, knowing whether the result is positive or negative is enough to determine <, >, or =.
That would only happen if the numerator in your final division equals zero. In this problem, we have a positive number after all operations, so the result is greater than zero.
Not recommended! It's better to work step by step through the operations, tracking signs carefully. This builds understanding and prevents errors in more complex problems.
