There are many ways to do this, Rose, and I am not sure that you have stated all the portions of the problem. Do we use only each number once? Must we use each number? Anyway, two ways are as follows. 5 times 5 is 25, subtract 1, equals 24. Another is to add 1 plus 5 equals 6, now 6 times 5 equals 30, now add 1 plus 5 again and get 6, finally 30 minus 6 equals 24. If there are some other limitations, perhaps you could let us know. Regards, Tom Bellows |

You can operate on the numbers however you like using the operators +, -, *, and / to get the number 24. |

Another problem of this variety (in the sense that the solution involves fractions) is to obtain 24 using the four numbers 3, 3, 7, and 7. It is possible, using only *, +, -, and / to do this, using each number exactly once. |

how on earth do you get the numbers 3 3 8 8 to equal 24... considering you can only use each number once...you have to use all four numbers and...you can only +, -, * and / |

>THIS IMPOSSIBLE? > >12, 13, 4, 1 = 24 > >ONLY USING THE ABOVE RULES, = , - , X , /, AND () AND YOU >MUST USE EACH NUMBER ONCE. It can be done (5-(1:5))* 5 = 24 |
