What are the rules for adding numbers whose signs are different?
Positive plus positive is positive. Negative plus negative is negative. Positive plus negative is positive if the absolute value of the positive number is greater than the absolute value of the negative one. Positive plus negative is negative if the absolute value of the negative number is greater than the absolute value of the positive one.
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.
Can a absolute value negative number must be less than the absolute value of a positive numbers?
No. The absolute value of negative nine is greater than the absolute value of 3.
How do you find the absolute the Absolute Value?
The absolute value of a number is the positive (or non-negative) value of the number. The absolute value of 0 or a positive number is the number itself. The absolute value of a negative number is its positive equivalent.
What is a negative plus a positive?
When adding a negative number to a positive number, you are essentially subtracting the absolute value of the negative number from the positive number. The result will have the sign of the number with the greater absolute value. For example, -3 + 5 would be equivalent to 5 - 3, which equals 2.
When you add a negative number to a postivie number it equals?
If the absolute value of a negative number is greater than the absolute value of a positive number, then on addition we will get a negative number. e.g. -4 + 1 = -3 If absolute value of positive number is greater, then the result is positive. e.g. 5 + (-4) = 1
Can a negative number be greater than a positive number?
No. All positive numbers are greater than zero and all negative numbers are less than zero. Therefore, all positive numbers are greater than all negative numbers. That said, there is a such thing as absolute value, which is how far a number is from zero. For example the absolute value of -10 is 10. The absolute value of a negative number can be greater than that of a positive number.
What is the sign for multiplication and addition?
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.

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 can you say about the sign of the sum of integers with unlike signs?
Positive + positive = positive Negative + negative = negative Positive + negative will take the sign of the number with the greater absolute value.
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.
How can a negative number be greater than zero?
if the negative number is within an absolute value sign than the negative number will actually equal a positive number
Can a absolute value negative number must be less than the absolute value of a positive numbers?
No. The absolute value of negative nine is greater than the absolute value of 3.
Is the absolute of a positive integer is a negative integer?
No. The absolute value of a number is the value of the number ignoring the sign - it is always positive: The absolute value of a negative number is a positive number; The absolute value of a positive number is a positive number.
A teacher wrote two numbers on the board negative 10 and positive 7 On the lines below explain which number has the larger absolute value and why?
Negative 10 because the absolute value of a number is the positive and negative form of that number. For example: The absolute value of 9 is positive 9 and negative 9. Therefore, it would be greater than the absolute value of any number below it.
What do you get when you add a positive and negative number?
First, subtract the absolute values of the integers, then use the greater absolute value's sign.
