Positive numbers, on your door. Negative in your freezer.
A negative. If you have a string of positive and negative numbers multiplied together, all you need to find the sign of the answer is to find the parity of the negative numbers. If there are an odd number of negatives then the answer is negative and if there are an even number of negatives then the answer is positive. Remember, positive numbers make no difference to the sign of the answer.
Pretend both the numbers are positive, find the quotient as normal and then make it negative.
By treating it as a positive number. Since negative numbers include the factors of their positive counterparts and all positive numbers are greater than all negative numbers, the GCF will always be positive. The GCFs of (3, 9), (3, -9), (-3, 9) and (-3, -9) are all the same: positive 3.

The same as with positive numbers. You need at least two numbers to find a GCF.
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.
Numbers are positive unless they have a minus sign (-) in front of them, in which case they are negative. As for the sum of positive and negative numbers, just add them up and find out. Add the positive, subtract the negative. It's very logical.
This is accomplished the same way as with positive integers. Add all of the numbers together and divide by (positive) 2. Don't let the negative signs fool you!
put the positive in front of the negative and just subrtact like to positive numbers. ex. x+(-y)= x-y

Multiply them. The answer will be negative.
A product is the answer when you multiply numbers or terms together. The product of two positive numbers is positive. ie. 2x2=4. The product of two negative numbers is positive. ie -(2)x(-2)=4 The product of a negative number and positive number is a negative number. ie. (-2)x 2=-4 In general, multiply the numbers as you normally would, and if the signs are different. the product is negative. If the signs are all the same, the product is positive. Remember that if a negative number is outside brackets, the question might be approached a bit differently.
