Assume there are approximately 5,000,000,000 (5 billion) people on Earth. What would you estimate to be the result, if you multiply together the number of fingers on every person's left-hands? (For the purposes of this exercise, thumbs count as fingers.) If you cannot estimate the number then try to guess how long the number would be?
5^(**********) if everyone had five fingers on thier left hand. But realistically there could be people with no hands, so even if one zero creeps up the whole product drops to 0.
If I multiply the three digits on car number plates together what number am I most likely to get? (e.g. 377, 737, 773 are the only plates to give 147 but 234, 243, 324, 342, 423, 432, 146, 138, etc all give 24)
There is a number which when you multiply by 3 and subtract 2 from the result, then the resulting number is the reverse of the actual number.
What is the smallest number that stands true on the statement?
