Hi Mark,

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!
