ABC

DEF

GHI

1. The sum of the top row is greater than the sum of the middle row, which is greater than the sum of the bottom row.

2. E is a prime factor of G.

3. F is greater than A.

4. The sum of B and G is equal to H.

5. I is not 1.

Very fun! Would love to see more like this :) | |

Thank you casteil! I will try to come up with more :) | |

LOLOL. Let's try again. c-a-s-t-i-e-l. :D | |

I came up with 8-5-4/6-1-9/2-7-3, forgetting that people don't consider 1 to be prime. Silly me. :lol: | |

Good try anyway EoG; I'm sure you'd have gotten it had you remembered the weirdness of 1 not being prime. It's debatably prime, really, but convention is to consider it non-prime -- mostly because it keeps the fundamental theorem of arithmetic simple to state. | |

I think I found alternative solution. A=5; B=7; C=6; D=4; E=2; F=9; G=1; H=8; I=3 | |

The only problem is, 2 is not a prime factor of 1. | |

I was smart enough to not even try this one. Besides that, I was never a math person. Got by in school with a passing grade and that was it for math. I did excellent in English and other subjects. Just not math! UGH! :( |
