Topic: Help on a math problem please!!! 


My daughter came home with what I think is a pretty tough math assignment. It may take some magic to solve but I though maybe someone would have some ideas. She needs to make a true subtraction problem using the numbers 1  9. All numbers must be used and can be used only once. Sample give was 486 359 _________ 127 Any help or ideas would be appreciated. She needs 15 examples. Thanks and have a nice day, Walking Bob in Iowa 


If she's allowed to get creative, how about: [code] .486 .359  .127[/code] [code] 4.86 3.59  1.27[/code] [code] 48.6 35.9  12.7[/code] BTW, if you have Martin Gardner's 3rd book, [i]New Mathematical Diversions[/i], check out Chapter 19 ("Nine More Problems"), where approaches to a similar problem are discussed in detail. There are some solutions discussed in that article, including: [code] 972 654  318[/code] and [code] 567 438  129[/code] Heck, if you want a computer to solve it for you, go to the [url=http://www.tkcscollins.com/truman/alphamet/alpha_solve.shtml]Alphametics Puzzle Solver[/url], and type in for the summand words: ABC DEF For the sum word enter: GHK You'll get the answers as addition problems, but that's easily turned around to a subtraction problem. Also, some of the solutions presented will use a 0, and that sounds like it's not allowed in the assigned problem, so make sure to skip those. 


Thanks Scott for the ways to solve this problem. Walking Bob
