10

Explanation:

The color(blue)"absolute value" is always color(red)"positive".

This is because it is a measure of how far a value is from zero.

"That is " |-4|=|4|=4 since both - 4 and 4 are 4 units from zero.

10

Explanation:

So absolute value means a number's distance from 0.
-10 is 10 units from 0, so the answer is 10.

An easier way to do this is to just get rid of the negative sign.

Here are some examples:

|31| = 31 (because 31's distance from 0 is 31)

|-31| = 31 (because -31's distance from 0 is 31)

You can do some practice by using random number generators and finding their absolute values.

+10

Explanation:

The format of |-10| is a way of mathematically stating the 'size' of a count. It does not matter if the number inside the | | is positive or negative. The size of the count is the same.

Example " "|-5|=|+5| = 5

A name for the 'count size' is Cardinality but at this level you will NOT be using this name.

The name for the color(red)(|" some number" |) is absolute value which you will be using.

color(brown)(|-10| =|+10|=10
