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.
