- You can't take three from two, two is less than three, so you look at
- the four in the tens place.
- Now that's really four tens, so you make it three tens, regroup,
- and you change the ten to ten ones and you add 'em to the two and get twelve,
- so you take away three, that's nine.
- Now instead of four in the tens place you've got three, 'cause you added one,
- that is to say, ten, to the two, but you can't take seven from three so
- you look in the hundreds place.
- >From the three you then use one to make ten tens, and you know why four
- plus minus one plus ten is fourteen minus one?
- 'Cause addition is commutative. Right! And so you have thirteen tens and
- you take away seven and that leaves five.
-
- Well, six, actually, but the idea is the important thing.
-
- Now go back to the hundreds place - You're left with two, and you take
- away one from two and that leaves...
-
- Everybody get one? Not bad for the first day.
-
- Hooray for New Math... New-w-w math...
- It won't do you any good to review math...
- It's so simple, so very simple
- That only a child can do it!
-
- Now the book that I got this problem out of wants you to do it in base eight.
- But base eight is just like base ten really... (see above quote)
- Shall we go for it? Hang on...
-
- You can't take three from two, two is less than three, so you look at
- the four in the 8's place.
- Now that's really four eights, so you make it three eights, regroup,
- and you change the eight to eight ones and you add 'em to the two and
- get 1 2 base 8,
- which is 10 base ten, so you take away three, that's seven.
-
- Now instead of four in the eights place you've got three 'cause you added one,
- that is to say eight to the two, but you can't take seven from three so
- you look in the 64's.
-
- 64?
- How did 64 get into it? I hear you cry.
- Well, 64 is eight squared, don't you see...
- ... Ask a silly question and you get a silly answer.
-
- From the three you then use one to make eight eights, you add those
- eights to the three and get 1 3 base eight
- Or in other words in base ten you have 11 and you take away seven and
- seven from eleven is four!
- Now go back to the 64's. You're left with two and you take away one from
- two and that leaves...
-
- Now let's not always see the same hands.
- One. That's right. Whoever got one can stay after the show and clean the
- erasers.
-
- New math! New-w-w math.
- It won't do you any good to review math.
- It's so simple, so very simple,
- That only a child can do it!
-
- Come back tomorrow night, we're gonna do... FRACTIONS.
