Fill in the blank: The smallest four digit number with four different digits is _______.
✓
Answer
Four smallest digits are $0, 1,2$ and $3$. In order to write the smalest $4-$digit number using digits $0, 1, 2$ and $3,$
we put the smallest digit $1$ (Except $0)$ at the place having the highest place value.
The largest digit $3$ is put at the right most place
i.e. at unit's place, the digit $2$ is put at the ten's place and the digit $0$ is put at the hundred's place.
Hence, the required largest number is $1023.$
The smallest four digit number with four different digits is $1023.$
