a and b are negative numbers.
Therefore, what kind of number is is a-b?
We test using an example:
We define that
a = -1
b = -2
Now we replace in the exercise:
-1-(-2) = -1+2 = 1
In this case, the result is positive!
We test the opposite case, where b is greater than a
We define that
a = -2
b = -1
-2-(-1) = -2+1 = -1
In this case, the result is negative!
Therefore, the correct solution to the whole question is: "It's impossible to know".
Impossible to know.
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
