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.
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.
What is the sum of a number and its absolute value?
It is either two times the number or 0.
Is the sum of a positive number and a negative number always negative?
no- it depends on the absolute values of the numbers. The sum is negative only if the absolute value ( the value without the sign) is larger than the positive number. example -98 + 100 is positive because 100 is larger than 98. -100 + 98 is negative because 100 is larger than 98.
When is the sum of two rational numbers with different signs positive?
The sign of the sum is positive when the absolute value of the positive addend is greater than that of the negative addend.

What is the sum of a number and its absolute value?
It is either two times the number or 0.
Is the sum of two integers positive or negative?
If for the two integers a + b = c, a is larger than zero and b is larger than the absolute value of the first number, then c is always positive. If a is smaller than zero, and b is larger than the absolute value of the second number, then c is positive. If a is smaller than zero, and b is smaller than the absolute value of the second number, then c is negative.

no- it depends on the absolute values of the numbers. The sum is negative only if the absolute value ( the value without the sign) is larger than the positive number. example -98 + 100 is positive because 100 is larger than 98. -100 + 98 is negative because 100 is larger than 98.
What is greater than the number in a pair?
The value of the sum of their absolute values is one possible answer.
Why does the mean absolute value deviation is calculated using absolute value?
if no absolute value is used the sum is zero.
When is the sum of two rational numbers with different signs positive?
The sign of the sum is positive when the absolute value of the positive addend is greater than that of the negative addend.
What is triangular inequality of complex number?
The absolute value of the sum of two complex numbers is less than or equal to the sum of their absolute values.
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.
When is the sum of a positive integer and a negative integers?
When the absolute value of the negative number is higher than the positive number.
What is the sum of two opposites?
If the negative has a greater absolute value, the sum will be negative. If the positive has a greater absolute value, the sum will be positive.
