Is the sum of an absolute value is the same of their absolute values?
The sum of the absolute values of two numbers is greater or equal than the absolute values of the sum. It will be equal if both are positive or both are negative; greater if one is positive and one is negative. Try it out with some sample numbers!
What are some characteristics of 'absolute value'?
Absolute value means disregarding the negative sign if it exists. So 5, +5, -5 all have the absolute value of 5.
What does the absolute value of a number mean?
The absolute value of a number is the distance that number is from zero.A more accurate description is to say the absolute value of a number is the value of the number regardless of its "+" or "-" sign, which is also known technically as its "polarity".Further notesThe "value" of any particular number means the quantity or amount of some things which that number represents.Just a few examples of some values are shown in bold below:5 apples for which the absolute value is 5-12 volts for which the absolute value is 121000 houses for which the absolute value is 1000-273 oC for which the absolute value is 2730.1 miles for which the absolute value is 0.1
What if you add a negative to a positive?
If you add a positive and a negative number, the result can be positive, negative, or zero - depending on which of the numbers has the greater absolute value. Here are some examples: 4 + (-4) = 0 (zero) 4 + (-6) = -2 (negative) 4 + (-2) = 2 (positive)
Why no order in complex numbers?
Basically you can have an order on a number line, but complex numbers are points on a plane. You can invent some arbitrary order, like which number has the largest real part, or the biggest absolute value, but many of the order properties of real numbers are no longer valid with such definitions.

What are some negative integers whose absolute value is greater than 3?
-5, -23. -235689 are three examples.

Can any negative integer be greater than a positive integer?
Some sources say that the answer is no because a negative integer is less than zero and a positive integer is greater that zero. This answer is partially incorrect because if a negative integer is in an absolute value problem, it can potentially be greater that a positive integer. Example: |-11| > 7 because |-11|=11 because it is in an absolute value problem. Simplified, the problem is 11 > 7 So yes, in some cases a negative integer is greater that a positive integer.

What Conditions necessary for a measure of variation to have a positive value?
It is that the measure is somehow related to the absolute value of the observations compared to some fixed value and also that there IS some variation.
What is some constant numbers that don't changes it's value?
well some numbers are 4,6,8
How do you find the mean of a group of numbers where some are negative numbers?
The fact that they are negative only means that you subtract their absolute value. So to get the mean of 5, 6 and -2 sum = 5 + 6 - 2 = 9 number of values = 3 mean = 9/3 = 3
What are some examples of when you might need to compare numbers?
when you want to compare numbers to which is greater, lower or even equal
What is the difference between the numbers 25 and 30?
the difference is negative 5 and the difference between 30 and 25 is 5. Some people look at the difference as absolute value so we have |25-30|=|30-25|=5
