Yes
The sum of three negative numbers is always a negative number. This is because adding negative values together results in a greater negative total. For example, if you add -2, -3, and -5, the sum is -10. Thus, regardless of the specific values, the result will always be less than zero.
The mean would be negative, but standard deviation is always positive.
That is false. A negative times a negative is always a positive. Since absolute numbers are always positive if you make it negative that is not correct.
This is not strictly true, because an absolute value, and hence the product of two absolute values can be zero. It is, therefore true to say that the product of two absolute values is always non-negative. An absolute value of a number is, by definition, non-negative. And by the definition of multiplication, the product of two non-negative numbers in non-negative.
No. A negative plus a negative will always be negative. Adding negatives just makes them more negative, just like adding positives makes them more positive.If you're thinking of multiplication, then the answer is yes. Like signs result in positive values. Opposite signs result in negative values.
No. Probability values always have to be positive.
No, absolute values are always positive.

Yes, percentages are always expressed as non-negative values. A percentage represents a part of a whole and is typically given as a value between 0% and 100%, although it can also be expressed as a number larger than 100% when indicating values greater than the whole. While the context of a situation may involve negative values (such as losses), the percentage itself is calculated based on absolute values, leading to a non-negative figure.
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
The absolute value is the distance from 0 on the number line. -5 is 5 away from 0. You cannot have a negative distance, therefore you cannot have a negative absolute value. Absolute values are not ALWAYS positive because absolute values can be zero as well. Zero is not positive nor negative.
Both absolute values and temperatures on the Kelvin scale do not have negative values. Absolute values represent the distance of a number from zero on a number line, always yielding a positive result. Similarly, temperatures on the Kelvin scale start at absolute zero, which is the lowest possible temperature with no negative values.
