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.
What happens when you add two opposites together?
The absolute value of the answer is the difference between the absolute values of the two numbers and the sign associated with it is the same as that of the number with the greater absolute value.
The difference of a negative integer and a positive integer is?
An integer that is equal in magnitude to the sum of their absolute values. Its sign is the same as which of the two numbers you are taking the difference from. For example, for the integers 5 and -7. Their absolute values are 5 and 7 so that the sum of the absolute values is 5+7 = 12. Then 5 - (-7) = +12 and -7 - 5 = -12.
The difference of the absolute value of two numbers is positive?
Yes. The absolute value of two numbers is ALWAYS positive. This is because absolute value means "the number of spaces a number is from zero on a number line.
Is this question true or false are there always two numbers thtj have the same absolute value?
Other than for the value 0, there are always two numbers that have the same absolute value: the number and the negative of the number, eg 2 and -2 both have the absolute value 2. There is no negative 0, so there is only the number 0 which has the absolute value 0.
