When subtracting values from the mean, you typically calculate the differences as either positive or negative based on whether the individual values are above or below the mean. Positive differences indicate values that are greater than the mean, while negative differences represent values that are less than the mean. This approach helps in understanding the distribution of data around the mean and can be useful in statistical analyses, such as calculating variance or standard deviation.
Positive. A negative number added to a positive would reduce the original to a smaller positive, to zero, or to a negative depending on their relative values but subtracting a negative number from a positive number will always increase the value of the positive.
adding or subtracting them, that would depend on the magnitude of the values; multiplying or dividing would yield a negative product or quotient
[ -2n ] is positive for all negative values of 'n' .

The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.

By doing this it aligns all the place values so you can clearly add or subtract the correct place values and get a correct answer. You might say it is an organization technique. Of course if you use a calculator, this is not necessary.

No. Probability values always have to be positive.
That depends on the values of the given numbers but a positive number multiplied by a negative number will be negative
Positive for nonmetals and negative for metals
Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.
If the points have both positive y-values and x-values it is quadrant 1 If the points have a negative x-value and a positive y-value it is quadrant 2 If the points have both negative y-values and x-values it is quadrant 3 If the points have a positive x-values and a negative y-value it is quadrant 4
