Question

Kyle purchased a padlock with a resettable combination that uses 3 digits from 0 through 9 that must be entered in the proper Order. A digit may be repeated in the combination. Which expression shows the total number of possible combinations for the padlock?

Answer 1

In the first position we have 10 possible numbers, and the same for the 2nd and 3rd positions becuase the numbers are replaced, so our answer is
`10^3=1000` because of the multiplication rule.
