Will the exercise result in a negative or a positive sign:
We are only concentrating on whether the number is negative or positive.
In other words, the exercise should look like this:
If we solve the exercise from left to right, we must first multiply the fraction:
Since the numerator of the fraction is positive and divides by the negative denominator, the resulting fraction will be negative.
Therefore the remaining exercise is as follows:
If we then multiply minus by minus, we should obtain a positive number:
The resulting exercise is:
Therefore, the resulting sign of the exercise will be negative.

What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
The fraction is one complete unit that must be calculated first. Think of it like solving what's in parentheses - you get +10, then divide +10 by -1.7.
Break it down step by step: negative divided by negative = positive, then positive divided by negative = negative. Count the negatives at each step!
That works perfectly for determining the sign only! You can ignore the numbers 4, 0.4, and 1.7, and just focus on:
Think of division as "how many times does the divisor go into the dividend?" When both numbers point in opposite directions from zero, the result points in the positive direction.
Absolutely! Calculate and see if your answer is negative or positive. This confirms your sign reasoning.
Both : and ÷ mean division - they're just different notation styles. In this problem, means the same as
