how many different four digit numbers can be formed by rearranging the digits of 2010?
~~~~~~~~~~~~~~~~~~~

Everything that does not start with "0" in the most left position.

It gives you 2*3*2*1 = 12 options.

And having two indistinguishable digits "0" forces you to divide 12 by 2! = 2.

In total, there are   = 6 options.  6 numbers.

Answer. 6 numbers.

They are

2100  1200
2010  1020
2001  1002
