    Because it is in the set of original numbers. 000 is a number with three digits. If you did not want to count 000 and other numbers with 0's in the front the answers would be: The first one is: 6*7*7 The second is: 6*7*4 The last is: 7*6*5

    Note the last one you should still count 012 and others like it because it only specifies 3 digits without repeating.

    c'est 3 puissance 7 (3^{7}) parce que chacun de ces 7 chiffres peuvent prendre n'importe quel position dans ce nombre à trois chiffres ex:111 122 112 112
