Transcript: How Many Rails for the Detour?

JACKIE: That's it. We've got tons of flowers. We're out of here.

MATT: Back to the tunnel! Are the tracks clear?

DIGIT: This cement is too hard!

JACKIE: Oh, man, now there's no way to get the flowers to the portal!

MATT: We let Motherboard down. Hacker won.

INEZ: Not yet, guys! We can go around the mountain!

JACKIE: But there's no rail for the train!

MATT: So? We'll lay down a new one - and connect it to the old one. We can do that!

DIGIT: Yeah! How much rail do we need?

INEZ: According to this, it's one point five rails from here to the next signal.

JACKIE: One point five...got it!

MATT: One point eight from here to the bridge.

INEZ: Plus two full rails to get across the bridge. Hmpf! That's all we need!

JACKIE: I'll add it up. Five and eight is thirteen plus two is fifteen...carry my one...for a grand total of...Three point five rails!

INEZ/MATT/DIGIT: Huh???

MATT: That can't be right, Jax.

INEZ: It has to be more! The sign said we need rails that are one point five long plus one point eight long and another that's two rails long.

MATT: Yeah. That's a least four whole rails.

DIGIT: May I? Remember, you have to add the same size pieces. Tens to tens and ones to ones.

JACKIE: Right.

DIGIT: This two is a whole number so it needs to be in the ones place. And where is the ones place? Over here - left of the tenths place. That's where. And it's not just two - it's two point zero. We write a zero here - 'cause there are no tenths. So, eight and five is thirteen. Carry my one. Now two plus one plus one plus the one we carried over is five... for a real total of...Five point three! To keep your places straight - you gotta keep your decimals straight!

JACKIE: Sorry, guys. I put the two in the wrong place.

MATT: Didge, you're a wonder!

DIGIT: I know that!
