Use tiles 1 to 9 to make a true equation.?

__ __ __


* __ __ = __ __ __ __





Can you find at least four differnt solutions?Use tiles 1 to 9 to make a true equation.?
Aliright, the best way to do everything is to start by using variables. ABC, a three digit number, times DE, a two digit number, = (DA)(DB+AE)(EB+DC)(EC), a four digit number. So wee need to find numbers A, B, C, D, and E such that A, B, C, D, E, (DA), (DB+AE), (EB+DC), (EC) are all different. And remember, it's not exactly like this, because if any of the parenthasee terms are %26gt;9, then the next term over will be whatever it is, + the second digit of that term.





This is a very hard problem, and i'm a little sick, and too tired to find a solution. this is something that's gonna take you a while, so have fun.
