Are you thinking along the lines of permutations or combinations?
Hey guys! Feel like this is a really simple problem that seems to be evading me.
So this problem is based around 4 digit products, of two 2-digit factors.I need to find 6 possible combinations where ab times cd = abcd. But it doesn't need to all be aligned. A visual example would be 12 x 34 =2341 ......if that were an actual solution... Any ideas?
