This question should put a little shmoop in your step...

00:06

What does the absolute value of negative 6.23 equal?

00:11

And here are the potential answers...

00:15

Ahh... translations... learning to speak...math.

00:21

So... let's pick this one apart.

00:22

These bar thingies are absolute value signs.

00:26

And we know this is a negative sign.

00:28

This here is a decimal -- often pronounced "point." In... "American," anyway

00:36

So we read the problem as "the absolute value of negative six point two three."

00:42

And as in all absolute value problems, it is only measuring how far the point is from the origin.

00:47

This thing. Number line.

00:50

It's always a positive number, so in this case, its 6.23 units

00:54

to the right from 0 on the Number Line...

00:56

...and the answer is E.
