Will the result of the exercise below be positive (+) or negative (-)?
In this question, we only need to work out whether the resulting value is negative or positive.
In other words, the division exercise can be considered as follows:
If we solve the exercise from left to right, we first divide the numerator of the negative fraction by the denominator of the negative fraction:
This leaves us with:
Therefore, the result of the exercise will be positive.
+
Solve the following exercise:
\( (+6)\cdot(+9)= \)
Think of division as "how many times does the divisor fit into the dividend?" When both numbers have the same sign (both negative), the result is always positive. It's like the rule: opposite signs attract, same signs repel!
No! The question only asks for the sign of the result. You just need to determine if it's positive (+) or negative (-), not the exact numerical value.
Work left to right for operations of the same priority. First solve , which gives you +0.5, then divide that result by 0.7.
Use this memory trick: "Same signs = positive, different signs = negative". Since both -4 and -8 are negative (same signs), their division gives a positive result!
Positive ÷ positive always equals positive. In this problem, after getting +0.5 from the fraction, you're dividing +0.5 ÷ +0.7, which stays positive.
