Question from Rajesh: What is small four-digit whole number? |
Hi,
A four digit number has four digits with one requirement, the thousands digit can't be zero. If it is then you have at most a three digit number.
Put a digit in each of the green squares above so that you have a four digit number. Can you write a smaller four digit number? What is the smallest four digit number you can write?
