I wrote an excel macro that listed all of the combinations of these 6 numbers in a string, with the x and = symbols mixed in every possible way. (The first combination was “1*2=4568” and the last one was “8654=2*1”) I then had the macro evaluate the equations and find the ones that evaluated to true. Out of the 18,000 combinations of numbers and math symbols, only 8 of them evaluated to true. The true combinations are…………..
416=52*8
416=8*52
512=64*8
512=8*64
52*8=416
64*8=512
8*52=416
8*64=512
(Note that there are only 2 distinct combinations that work. The macro found all the ways that you can express those 2.)
