Transcript: Several Short Rails Can Make More Than One Whole Unit

DIGIT: Hey, Deci... Deci! Where is that guy? Ah, never mind, I gotta find those rails! Wu-oh, no more short ones! Brain-spark! I’ll just add these numbers like any other numbers - and get one big rail! No problem! Six and two is eight. Eight plus four is...twelve! The answer is twelve! Just pop in the decimal point and... and, wu-oh, where do I put it? Here? Over here? Between here? Boy! I know I gotta put a decimal point somewhere...but where?! Think, Digit...think! Opf! Deci! Am I glad to see you! Hacker messed up the track again - and I need a rail that’s twelve somethings long!

DECI: Twelve somethings??? Where’s your decimal point?

DIGIT: That’s just it...I DON’T KNOW WHERE IT GOES!

DECI: At ease, Didge. Show me the numbers you added. Your addition is first rate! All you need is the right place for the decimal point. Hold out your wings! These are the same length as the rails you need. Point six...point four...point two! Now slide ‘em in here.

DIGIT: Point six...plus point two makes point eight. Plus point four...uh-oh! The point four sticks out past the top!

DECI : Exactly! Because you have more than ten in the tenths place! Try putting in the decimal point two last.

DIGIT: Okay. Point six...plus point four makes...a full tube! Point ten?

DECI: Hold on. You mean ten tenths – one whole tube.

DIGIT: And I’ve still got point two left over! Wait a minute! That gives me one whole...and two tenths!

DECI: Exactly. Perdone.

DIGIT: I don’t have twelve - I’ve got twelve tenths! Which is the same as ten tenths plus two tenths. Or...One point...two! I’m a genius! The point goes between the ones place and the tenths place!

DECI: That is kee-rect, sir! Watch where you put your decimal point - and you’ll always know your place!

DIGIT: So what I need is a one point two rail!

DECI: Affirmative!
