Then hang on tight!

[Not that Clay's gonna go particularly fast or anything. He's got to keep count in his head about how far he's going, after all. He keeps his gaze down on his feet as he moves forward; his feet aren't a foot long, that'd be kind of too huge. But he can make a pretty good estimate based on the size of them as well as a few additional inches.]

Take a look at your thumb. You see the line below your thumbnail? That's your first knuckle, and that's about an inch there. Twelve of those make a foot, and we're going a hundred feet away from the stick! So, how many inches, or thumb knuckles, would you need to get to a hundred feet?

[Bran looks down at his stubby little fingers, and tries to follow along. He learned simple sums, of course, but it takes him a moment to figure this one out.]

... Twelve-hundred?
geonomy: (☆ our day has come)

[Oh man, he's so glad that kids like these learned simple maths. He grins, a little bit of a bounce to his steps even as he's carefully trying to figure out how many more steps he has to take.]

That's right! Twelve times one-hundred is twelve-hundred! When you're multiplying by ten, one-hundred, or one-thousand, all you have to do is carry however many zeroes you have to the end of the number you're multiplying.

[Unless there's decimals and whatnot, but that's a bit more complicated.]

So, in other words, twelve-hundred inches would be...

[And he stops, turns around, and shows Bran the distance between where they are and how far away the stick is.]

That far!

How many inches is four hundred feet?

[He looks up at the trees. They look a lot taller than the distance to that stick...]

[The kid's so eager to learn, and Clay loves that. He grins, then turns to start walking carefully again. Gonna be a much longer walk!]

Alright, so let's go over it again. How many inches are in a foot?
summerschild: (♜ holy light oh burn the night)

[personal profile] summerschild 2016-07-01 06:33 pm (UTC)(link)
Twelve.

[He thinks, and thinks.]

Twelve, but four times, and then you... carry the zeroes?
geonomy: (☆ sink in the river)

[personal profile] geonomy 2016-07-01 06:35 pm (UTC)(link)
Yeah, exactly! You leave the zeroes off until you multiply twelve times four.

So, what is twelve times four?
summerschild: (♜ let me hear you sing)

[There are no multiplication tables in Westeros - only sums - so it takes him several moments to add up all the twelves in his head. But finally, he looks up at Clay hesitantly.]

Forty... eight?
geonomy: (☆ but baby i've been praying hard)

[personal profile] geonomy 2016-07-01 06:48 pm (UTC)(link)
[And he rewards Bran with a beaming smile, and for a second, he takes moves his supporting arm to give Bran's hair a ruffle before he goes back to holding the wheelchair properly.]

That's it! Twelve times four is forty-eight!

Now, all we do is add the zeroes to the end of it. And since there's two zeroes in one-hundred...
summerschild: (♜ oh keep the spirits strong)

[personal profile] summerschild 2016-07-02 12:35 am (UTC)(link)
Forty-eight hundred inches!

[He looks very pleased with himself.]
