Question

If two numbers have different numbers of digits,which one is greater ? explain how you know

Answer 1

I assume u are talking about natural numbers.

The number with the most digits will be the greater.

Because each digit starting from the rightmost represents some number of units, tens, hundreds, etc ( ie a 3 digit number is at least 100 and therefore bigger than any 2 digit number and the same argument applies to each successive place)
