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 <br>-.359 <br>----- <br> .127 Code:
4.86 <br>-3.59 <br>----- <br> 1.27 Code:
48.6 <br>-35.9 <br>----- <br> 12.7 BTW, if you have Martin Gardner's 3rd book, New Mathematical Diversions, 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 <br>-654 <br>----- <br> 318 and Code:
567 <br>-438 <br>----- <br> 129 Heck, if you want a computer to solve it for you, go to the Alphametics Puzzle Solver, 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. |
