Hi, .

Please see below a question on my 11 year old daughter's exam paper that we have no idea of the answer.

Find two numbers which when multiplied together make a thousand. neither of the two numbers must use any zeros.

Then, find two numbers which when multiplied together make a million. again neither of the two numbers must use any zeros.

Is there a quick way to do this rather then guess numbers a multiply them?

Thanks

Alvina
