No. you could have, for example, -4 or 4 (or any other minus or positive number).
Both are integers.
right
Progresssion... You are moving into the 2nd quadrant with two positives. Wait until trig class, then you will get it...
It will be the same as dividing positives but if it is a negetive divided by a postive the answer will still be negative
Multiply the negatives and subtract from the sum of the positives.
for the negatives its -2 or for the positives its +6. you can put any number just not zero

3 positives will be positive. 3 negatives will be negative.

Yes, by definition, the sum of two integers is always an integer. Likewise, the product and difference of two integers is always an integer.
The product of 2 (or more) positives is positive. The product of 2 negatives is positive. So product of 6 negatives = 3*(product of two negatives) = product of 3 positives = positive. So overall sign is positive.
Yes
the sum of two negative integers is ALWAYS negative
That is false. The product of two negative integers is always positive.
