It must be either, otherwise it is systematic error or bias.

Is a negative plus a positive a positive?

If, and only if the positive value is > the negative value.


Does -3x have a positive or negative value?

It depends on what the value of x is. If x is a positive number, then it will be negative because a negative number multiplied by a positive number is negative. If x is a negative number, then it will be positive because the product of two negative numbers is always a positive number.


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.


Can percent error be negative?

Sometimes you will take the absolute value of the percent error because your estimated number could be less than the theoretical, meaning the calculation is negative. But an absolute value is always positive. A percent error can be left as a negative though, and this would be perfectly acceptable (or even preferred) depending on what you're doing.Answer:In the sciences, a negative percent error indicates a low result. If you have a 0% error, then your observed (lab) result was exactly the same as the theoretical result. A 5% error could mean that your observed result was a little high. A negative percent error is possible; if your observed results were lower than the expected, then you would have a negative percent error. A -5% error could mean that your results were a little low. Having a negative percent error isn't worse than positive percent error -- it could mean the same thing. If you were to have a choice in having a 20% error and a -5% error, the negative percent error is more accurate.


An absolute value of a number can be positive or negative?

The absolute value is only ever positive. * * * * * Or 0.

Can absolute error be negative?

No because taking the absolute value of a number always yields a positive value.


Does a positive value multiplied by a negative value equal a positive?

No, the product of the multiplication of a positive and a negative value is negative.


Is a negative plus a positive a positive?

What does a negative add a positive equal?

If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.


Percent error formula?

Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.


Will the product of a positive and a negative factor be a positive or negative value?

What is the negative of zero?

There is no negative of zero, nor is there a positive. Zero is no value, hence it has no positive or negative value.

Negative PLUS a positive equals?

It is a negative if the negative number has the higher absolute value and positive if the positive number has the higher absolute value.


What is the absolute value for the positive?

What does it mean if you get a negative number when you calculate for percent error?

Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.


When is the sum of a positive and negative integer negative?

When the absolute value of the positive integer is smaller than the absolute value of the negative one.
