And here's your shmoop du jour.

00:07

Of all the absolute values of the following numbers, which would be the greatest?

00:12

Here are the potential answers...

00:14

Before we spoil the ending and kill all the drama... why not hit pause and try to solve this one yourself first?

00:20

OK, this question is just testing whether

00:22

we can use a number line and do some simple conversions...

00:26

...er, these conversions...

00:28

...and that we know what absolute value means.

00:35

To refresh our memories... absolute value is just the quantity of units of any number

00:39

from 0 on the number line.

00:42

Doesn't matter whether we're going in a positive or negative direction -- it's

00:45

only about how far we travel. So let's start by just converting these

00:49

numbers into decimals, so they'll fit.

00:52

Look through the potential answers.

00:53

A is -1 tenth, or -.1, and it goes here on the line.

00:58

But since it's only the absolute value we care about, we'll put it on the positive side.

01:03

B is negative .05, but on the positive side of the line it goes here --

01:08

and is clearly less than .1.

01:11

C is .02 and goes here and yeah, if you haven't figured it out by now, we can ignore the minus signs.

01:18

And finally we have D at .01 and it goes here.

01:21

So the answer is A.

01:23

Point one is furthest away from the origin and has the biggest absolute value.
