# Transcript: Lattice Have Fun

(Music plays)

An animated clip shows a big orange X on a blue background. It explodes and letters and numbers come out of it in all directions and float around.

Mathemagician Eric appears on screen. He’s in his mid-twenties. He has short dark brown hair and a beard. He wears a red T-shirt with the show’s logo, blue jeans and red Tennis shoes.

The screen turns red and the logo of the show appears next. It reads "MathXplosion." Meanwhile, cones, cubes and dices float around it.

Kids voices sing a song with lyrics that go

WHAT A HIT

IT'S NOT A TRICK

IT'S MATHXPLOSION

JUST FOR YOU

COOL AND NEW

MATHXPLOSION!

The episode starts with Eric standing in a workroom, this time he’s gardening.

Eric says OH, HEY.

IN GARDENS, YOU MAY COME

ACROSS BEAUTIFUL LOOKING

LATTICE LIKE THIS.

BUT DID YOU KNOW THAT

THERE'S AN AMAZING TRICK

FOR TWO-DIGIT

MULTIPLICATION USING

LATTICES THAT WILL HAVE

FRIENDS AND FAMILY THINKING

YOU'RE TOTALLY MAGICAL?

AND IT'S HUNDREDS

OF YEARS OLD.

(music plays)

He puts a small fence on one of the vases and then takes two tennis balls.

He says MULTIPLICATION.

(music plays)

Now Eric is ready for a new project.

He says PRESENTING THE LATTICE!

He shows the graphic of a grid on the floor.

He says WELL, IT'S REALLY ONLY A

SIMPLE 2 X 2 GRID, WITH

THESE FABULOUS SUPER LONG

DIAGONAL LATTICE LINES.

SO HERE'S HOW YOU DO THIS:

TAKE A TWO-DIGIT NUMBER,

SAY, 34, AND YOU WANT TO

MULTIPLY IT BY ANOTHER

TWO-DIGIT NUMBER, LIKE 55.

A caption on screen reads "34 times 55."

He says WATCH THIS.

WE ARE GOING TO USE

THIS LATTICE GRID

TO HELP US MULTIPLY.

HERE WE GO.

YEAH.

I'M GOING TO START WITH

THIS FOUR AND THIS FIVE.

MULTIPLY THEM TOGETHER

AND YOU GET 20.

He adds two number 4 on top and two number 5 to the side. Then combines the boxes and comes up with the numbers that he writes inside. The first one is 20.

He says SO I'LL PUT THE 2 ON ONE

SIDE OF THE LATTICE, AND

THE 0 ON THE OTHER SIDE.

SEE HOW THE LATTICE LINES

SEPARATE THE TWO DIGITS?

THEN, OVER HERE, 4

MULTIPLIED BY 5 IS 20.

SO AGAIN, I'LL PUT A 2 ON

ONE SIDE OF THE DIAGONAL,

AND A 0 ON THE OTHER.

3 MULTIPLIED BY

5 GIVES ME 15.

AND 3 MULTIPLIED BY 5

GIVES ME 15 ONCE AGAIN.

So now the grid has two rows that read 15 and 20.

He says WHEW.

THE LATTICE GRID

IS FILLED IN.

NOW, HERE COMES THE

SUPER AMAZING PART.

BEGINNING AT THE BOTTOM

RIGHT CORNER, START TO ADD

THE DIGITS UP IN EACH

DIAGONAL COLUMN.

THE FIRST ONE IS EASY

BECAUSE IT'S A 0 BY ITSELF.

THIS IS THE 1'S SECTION.

THIS NEXT COLUMN

REPRESENTS THE TENS.

SO THE 0, 2, AND 5 ARE

REALLY 0, 20, AND 50.

ADD THOSE UP, AND YOU

GET 70, OR 7 TENS.

NEXT IS THE HUNDREDS COLUMN.

WE HAVE 2, 5, 1.

ADD THEM ALL UP AND

YOU GET A TOTAL OF 800.

HOW MANY HUNDREDS IS THAT?

YOU GOT IT, 8.

I'LL WRITE THAT DOWN HERE.

AND OVER HERE IS A 1 ALL BY

ITSELF IN THE THOUSANDS COLUMN.

HOW MANY THOUSANDS

ARE THERE?

YEP, JUST ONE.

READ ALL THOSE NUMBERS

TOGETHER AND...

As he writes down the numbers, they blink on screen.

Next, he says THERE WE GO.

IN A SNAP, I NOW KNOW THAT

34 MULTIPLIED BY 55 EQUALS

1,870.

(music plays)

Eric draws a circle and colours it inside. He taps on it and a new clip plays. A world animated map appears on screen. Next, it concentrates on Italy and the Middle East. As mentioned, pictures of the different cultures appear.

Eric says LATTICE MULTIPLICATION HAS

BEEN AROUND FOR CENTURIES.

THE STORY GOES THAT IT

WAS BROUGHT TO ITALY

FROM THE MIDDLE EAST.

THERE, IT WAS

CALLED SHABACH.

AND IN ITALY, IT

WAS CALLED GELUSIA.

LATTICE MULTIPLICATION,

IT'S NOT MAGIC, IT'S MATH.

A big explosion brings the show’s logo back on the screen.

(music plays)

The end credits roll.
