Suppose you had $10 and you wanted to divide it equally among 10 of your friends. Each friend would get$1 since 10 × $1 =$10.

Suppose you had $100 and you wanted to divide it equally among 10 of your friends. Each friend would get$10 since 10 × $10 =$100.

Suppose you had $1,000 and you wanted to divide it equally among 10 of your friends. Each friend would get$100 since 10 × $100 =$1,000.

Suppose you had \$1,000,000,000,000 and you wanted to divide it equally among 10 of your friends. How much would each friend get?

Mark,

Not till I know where you are writing from! In Britain a trillion means a million million million, 1 followed by 18 zeros. In North America it's a thousand thousand million, 1 followed by 12 zeros.

Dividing a number that ends in zero by 10 has the effect of removing one of the zeros: so 3000 / 10 = 300.

So a British trillion divided by ten is 1 followed by 17 zeros, which is a hundred thousand billion. In North America it would be 1 followed by 11 zeros. What would that be called? Fill in the next two lines and find out!

 1 one 10 ten 100 one hundred 1 000 one thousand 10 000 ten thousand 100 000 one hundred thousand 1 000 000 one million 10 000 000 ten million 100 000 000 one hundred million 1 000 000 000 one billion ... ... ... ...
