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.

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.

You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.

The sign of the larger number will be the sign of the answer, if you're adding them together. If they're the same size, and of different signs, the answer will be zero.

First, look at the length of the numbers. If one is longer than the other, the difference is positive. If the numbers are of equal length, compare the first digits to see which is higher. Continue through the number and if all are equal, the difference is zero.

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

any two negative numbers multiplied together equals a positive number. any two positives numbers multiplied together equal positive numbers and any negative and positive numbers multiplied together equals a negative.negative, negative = positivenegative, positive = negativepositive, positive = positive

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

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

The quotient is what you get when you divide two numbers. If both numbers are positive, the quotient will be positive. If both numbers are negative, the quotient will be positive. If one number is positive and one number is negative, their quotient will be negative.

No. The product of two opposite numbers is always negative. Negative x positive = negative and Positive x negative = negative

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

Actually it does, whenever you mulitply and divide two negative and two positive numbers they always equal a positive number. When you multiply and divide a negative and positive they always equal a negative number.

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

It is positive. Any product of an even number of negative numbers will be positive, regardless of how many positive numbers you have. Similarly any product of an odd number of negative numbers will be negative, regardless of how many positive numbers you have.

Actually the set of integers is the same as the set of whole numbers since the whole numbers include negative whole numbers and zero.

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

If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.

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.

'cuz

Same way you do division with positive numbers. Then, if both numbers are negative, the result is positive, otherwise it is negative.
