Chapter 4 Complex Numbers
... The last sample problem of the previous section was rather long and tedious. It would be nice if some method existed by which the amount of work needed for this and other similar problems could be reduced. It turns out that it is indeed possible by using some elementary real number properties. The t ...

... be 7 and 6, respectively. This leaves 5 as the first digit of m and 4 as the first digit of n, and we have d=m-n=50123-49876=247 . Answer: 247 7. In any multiple of 9, the sum of the digits is also a multiple of 9. In order for our multiple to be as small as possible, the digits, starting from the ...

Problem of the Week Problem D and Solution Digit Product
... Let N be the smallest positive integer whose digit product is 2000. In order to find N , we must find the minimum possible number of digits whose product is 2000. This is because if the integer a has more digits than the integer b, then a > b. Once we have determined the digits that form N , then th ...
