What are the rules for adding a positive and negative integer?
The magnitude of the sum is the difference between the magnitudes of the two numbers. The sign of the sum is the sign of the number with the larger magnitude. (The "magnitude" of a number is just the size of the number without any sign.)
What is the absolute value of -7.61?
Absolute value of any number is just the magnitude without any sign attached to it. For positive numbers the magnitude is the value of the number. For negative numbers just remove the negative sign and you will have the magnitude. In this case the magnitude is 7.61
When subtracting and adding integers how do you decide what the sign of the answer will be?
The answer will have the same sign as the number with the larger magnitude.
What is a positive add a negative?
The sum will have the same sign as the number with the largest magnitude. If the numbers have the same magnitude, then the answer is zero, which is positive.
What is the rule of adding integers with unlike signs?
The magnitude of the answer is the difference between the two numbers and it has the sign of the integer which has the bigger magnitude. I guess so?
