How to solve it (Biggest digit, biggest place): Greatest number: write the digits from biggest to smallest. Smallest number: write them from smallest to biggest — but a number cannot start with 0, so put the smallest non-zero digit first and the 0 next. Place value = the digit × the value of its place (ones, tens, hundreds, thousands).
