Best Answer

The sum of two positive numbers is always positive, and the sum of two negatives is always negative. If you have a positive and a negative number, there sum can be either, so look at the absolute values to decide. For example -3+2=-1. Since all you care about is the sign, look at the absolute value. If the negative number has a greater absolute value, the sum is negative and if the positive number's absolute value, which is the number itself, is bigger, the sum is positive. If the absolute values are equal, the sum is 0.

The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.

Actually it doesn't. Add two positive numbers, and you always get a positive result.

Negative number and positive numbers are all numbers. Negative numbers are just positive numbers multiplied by -1.

Negative * positive = negative Positive * positive = positive Negative * negative = positive

It will still perform the calculation. The SUM function can deal with positive and negative numbers and it will deal with negative numbers correctly. So there will be no problems or errors if there are negative numbers amongst the numbers in the range of cells that it is calculating.

Negative because product of 47 negative numbers is negative and product of three positive number is Positive , so negative*positive = Negative.

'cuz

(The product of 33 negative numbers) x (2 positive numbers) = (negative sign) x (positive sign) = negative sign

Positive x Positive =Positive Positive x Negative= Negative Negative x Positive= Negative Negative x Negative =Positive

The negative sign will change to a positive sign when subtracting negative numbers from positive numbers so you will simply add them together.
