10 x 10 = 100 a hundred ©

10 x 10 = 100 a hundred = 10 2 ten to the two ©

This is called an array ©

Now let’s count arrays

So how many Cubes altogether? ©

10

1000 cubes

10x10x10 = 1000 a thousand ©

10x10x10 = 1000 a thousand = 10 3 ten to the three ©

10x10x10 = 1000 Fill in your TABLE = 10 3 ten cubed ©

Now how about? ©

10

10x10

10x10x10

10x10x10x10 = ?

10x10x10x10 = 10,000 ten thousand

10x10x10x10 = 10,000 ten thousand = 10 4 ten to the four ©

©

and take 1000 of these ©

©

If every green box contains 1000 red ones

Every box contains 1000 little boxes so 1,000,000 all together 10x10x10x10x10x10

Every box contains 1000 little boxes so 1,000,000 all together 10x10x10x10x10x10 = 1000 x 1000

Every box contains 1000 little boxes so 1,000,000 all together 10x10x10x10x10x10 = 1000 x 1000 =1,000,000 =10 6 ©

What about a billion ©

10x10x10 x10x10x10x10x10x10 = 1,000,000,000 =10 9 a billion ©

If you think that’s a big number how about

©

with 22 noughts or zeros ©

10 22 ©

You swallow molecules of air every time you breathe in ©

If you think that’s a big number how about

© 100 zeros 1

©

NOW

THAT’S

BIG ©

and it’s called a GOOGOL
