How do you evaluate #abs(-10)#?

Answer 1

#10#

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.
#rArr|-10|=10#

#10#

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

Simply removing the negative sign would be a simpler method to accomplish this.

Here are a few instances:

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

You can practice by determining the absolute values of random numbers generated by random number generators.

Answer 3

+10

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#

Cardinality is another term for the "count size," but you won't be using it at this level.

The name for the #color(red)(|" some number" |)# is absolute value which you will be using.
#color(brown)(|-10| =|+10|=10#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
