Greetings Four Fours Game fanatics…you know who you are…(BTW, if you aren't familiar with the Four Fours Game, the attached document includes a complete description)
I have been dinking around with the Four Fours Game since Algebra I in 8th grade in the early 1970s, when our teacher, the extraordinary Mr. Sherard, dropped it on us and made it a contest. In the early 1990s, I began the process of documenting my own hand-written solutions using the Equation Editor in MS Word. The current version, which I published two years ago to give to my math teacher friends, is still an MS Word/Equation Editor document. The current version contains multiple solutions for every number from 1 to 300. I am working on 301–400 as time permits. There is one source on the internet (mentioned in my document) that has single solutions up to about 40,000 and there was no way I could directly compete with that, which is why I decided to concetrate on multiple solutions for every number.
Although it would be possible to present these solutions using Mathcad, I have no desire to redo the existing work.
Here is Version 4.0 of The Four Fours Game, dated September 19, 2021. This document has a lot more information than the previous version and includes more than 3,400 solutions for all integers from 1 to 500. Enjoy.
