# Three-digit numbers

We have digits 0,1,4,7 that cannot be repeated. How many three-digit numbers can we write from them? You can help by listing all the numbers.

Correct result:

n =  18

#### Solution:

$n=3 \cdot \ 3 \cdot \ 2=18$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
