# Transcript: Old Math is New Again

(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 in front of a board with antique representations and objects dated. There’s a pyramid, a frog, a flower and a stone stick. He holds a blue ruler in his hands.

Eric says OH, HEY!

DID YOU KNOW

THAT LONG AGO

ANCIENT EGYPTIANS

HAD A CLEVER WAY

TO MULTIPLY

BIG NUMBERS?

IT'S DIFFERENT FROM

THE WAY WE USUALLY

DO MULTIPLICATION TODAY, BUT

THE NUMBERS ALL ADD UP.

AND THAT IS NO ILLUSION.

The blue ruler suddenly flies up and disappears.

Eric says HERE'S THE SECRET TO HOW ANCIENT

EGYPTIANS WOULD MULTIPLY.

FOR EXAMPLE:

He now writes some numbers on the floor using a white chalk. He writes "18 times 53."

Eric continues

THEY WOULD USE

ADDITION AND DOUBLING.

WATCH THIS... SO COOL.

MAKE TWO COLUMNS.

WITH THIS METHOD

YOU ALWAYS START

WITH A 1 IN THE

LEFT COLUMN.

PUT YOUR OTHER NUMBER, 53,

IN THE RIGHT COLUMN,

AND GET READY

TO DOUBLE.

ON THE LEFT,

DOUBLE 1.

IN OTHER WORDS,

1 PLUS 1

AND YOU GET 2.

DOUBLE 2.

2 PLUS 2, YOU GET 4.

DOUBLE 4 IS 8.

DOUBLE 8 IS 16

AND STOP.

He makes a column under the number 18 and adds the numbers 1, 2, 4, 6 and 16.

Eric continues

STOP DOUBLING WHEN YOU

REACH THE NUMBER

THAT IS MORE THAN

HALF OF THE NUMBER

YOU'RE MULTIPLYING BY,

WHICH IS 18,

BUT WITHOUT

GOING OVER.

LET'S SEE,

HALF OF 18 IS 9.

AND 16 IS LARGER THAN 9,

SO I'LL STOP THERE.

THE SAME THING WITH THE

COLUMN OF THE RIGHT.

HERE GOES...

I DOUBLED 53.

IN OTHER WORDS,

53 PLUS 53,

YOU GET 106.

DOUBLE IT,

YOU GET 212.

KEEP ON

DOUBLING, 424.

DOUBLE THAT

NUMBER, 848.

AND THAT'S THE BOTTOM OF

THE COLUMN, SO STOP.

Under the number 53 he writes the numbers and 53, 106, 212, 424 and 848.

Eric continues

WATCH CAREFULLY.

THIS PART'S

PRETTY COOL.

FIND THE NUMBERS

ON THE LEFT SIDE

THAT ADD UP TO 18.

THE ONLY WAY IS

2 PLUS 16.

The numbers 2 and 16 blink.

He continues

NOW, CROSS OUT ALL

OTHER NUMBERS

IN THE LEFT AND

RIGHT COLUMNS.

He crosses out numbers on both columns leaving the pairs for 2 and 106, 16 and 848.

Eric continues

WE'RE LEFT WITH 2 PLUS 16

EQUALS 18 ON THE LEFT.

AND 106 PLUS 848

ON THE RIGHT.

ADD THE TWO NUMBERS

IN THE RIGHT COLUMN.

He now adds a third column where he makes the addition of some of the numbers. He writes "106 plus 848 equals 900." Next, he writes "900 plus 40 plus 14 equals 954."

Eric continues

106 PLUS 848

EQUALS 954.

WAIT, WE'RE NOT

DONE YET.

JUMP INTO THE MODERN WORLD

AND VERIFY YOUR ANSWER.

He pulls out a gigantic calculator and does the maths again to check.

He says 18 TIMES 53.

FASTER THAN YOU CAN SAY

"BUILD ME A PYRAMID."

18 TIMES 53 EQUALS...

HA, 954.

AMAZING.

(music plays)

Eric appears now next to a big blackboard. The board turns into a screen and it introduces a clip that compares a modern computer with ancient Egyptians.

Eric says WOULD YOU BELIEVE THAT

MODERN COMPUTERS

AND ANCIENT EGYPTIAN MATH

HAVE SOMETHING IN COMMON?

IMAGINE LOOKING DEEP INSIDE

YOUR PHONE OR COMPUTER.

THERE ARE LOTS OF BINARY

NUMBERS - 0s AND 1s - IN THERE.

The dynamic clip shows a cartoon of Eric looking at numbers and calculations pass by above him on a black background.

Eric continues

TO MULTIPLY TWO

NUMBERS TOGETHER,

THE COMPUTER DOES

SOMETHING VERY SIMILAR

TO WHAT THE

EGYPTIANS DID.

IT USES ADDITION TOO.

THIS IS HOW COMPUTERS

SEE THE QUESTION 18 TIMES 53.

I GUESS GREAT MATH

MINDS THINK ALIKE,

EVEN WHEN THEY LIVED IN

DIFFERENT COUNTRIES

AND CENTURIES.

The clip shows the cartoons of Eric and the cartoon of an Egyptian looking at each other from opposite mid-screens.

Eric says YOU CAN ABSOLUTELY

TRY THIS AT HOME.

SHOW YOUR FRIENDS

HOW TO MULTIPLY

LIKE AN ANCIENT

EGYPTIAN.

IT'S NOT MAGIC;

IT'S MATH.

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