The sum of a positive and a negative number depends on the size of those numbers. It's like they are competing gangs. The positives don't like the negatives and vice versa. So they will fight. You take the two numbers and subtract the smaller one from the bigger one. WHich ever "gang" was bigger wins, so whatever is left over gets to keep their sign. For example -7 + 5. 7-5=2, but there were more negatives, so it is -2.

Is the the sum of a negative number and a positive number always positive?
No
How can you decide if the sum of two numbers is positive negative or zero without calculating the sum?
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.
How can you decide if the sum of two numbers is positive negative or zero without actually calculating the sum?
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.
Dose a negative number plus a negative number equal a positive number?
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
Is the sum of a positive and negative number always positive?
No. Such a sum can be positive, negative or zero.
Negative number plus a positive?
If the negative number is bigger then the sum would be negative.If the positive number is bigger then the sum is positive.
Why is the sum of a positive integer and a negative integer is always negative?
It isn't always negative. ... for example: -5 + 12 = 7 (a positive number) -5 + 2 = -3 (a negative number) -5 + 5 = 0 (neither negative nor positive) If the negative number has greater magnitude than the positive number, the sum will be negative If the positive number has greater magnitude than the negative number, the sum will be positive If the negative and positive numbers have the same magnitude, the sum will be zero.
Is it true that the sum of a negative integer and a positive integer is always positive?
It depends, if a number with positive integers is greater than the number with the negative integer therefore the sum will be in positive integer. And if the number with positive integer is less than the number with the number with negative integer then the sum will be in negative integer.
When a positive number and a negative number are added together the sum is if the positive number has a greater value?
If a positive and negative number are added together, and the positive number has a greater value, the sum will be positive.
Is the the sum of a negative number and a positive number always positive?
No

Not necessarily; a positive number plus a negative number will be a positive number if the positive number is greater. Example: 10 + (-6) = 4
How do you know when the sum of a positive integer will be negative?
The sum of two positive numbers is positive. The sum of two negative numbers is negative. The sum of a positive and negative number will depend on which number has a greater absolute value. 5 + (-4) = 1 5 + (-9) = -4
Is the sum of a positive number and a negative number always a positive number?
No

How does the sign of the product of the positive and a negative number compare withe the sign of the sum of a positive and a negative number?
The product of a positive and negative number is always negative The sum of a positive and negative number depends on which one is larger; subtract the two numbers and take the sign of the larger
When is the sum of a positive integer and a negative integer negative?
When the absolute value of the negative number is higher than the positive number.
