Question: I have a math puzzle. I have been working on it for over 2 weeks. Here it is: use the numbers 1-25 each only once. The rows across are an equation and the columns down are an equation. There are 25 boxes. You have to use the order of operation x and / first then = and -. Some of the answers are -numbers.
b= Blank These were black squares on the puzzle.
The rows and columns have to equal the answer across and down. I tried to do the -numbers first. I then tries to work backwards from the answer. I tried factoring the number and using the answers. I got 7 of the equations done and the remainng numbers wont work. I would apreciate any help I can get. All this work for 10 POINTS. I would rather write a paper on a great mathamatician.
We would also rather write a paper on a great mathematician. There seems to be no way to get around checking zillions of possibilities.
On the other hand, puzzles like that one are easy to invent: Just write down the numbers from 1 to 25 in a table in any order:
Then put in division signs first, where they fit, and fill up the rest with other operations:
Then solve the operations on rows and columns and hide the numbers:
Voila! you have a puzzle as tough as the previous one, and you can throw it back at whoever assigned that monstrosity.Claude
