If the letters T*(RBJBR)=VPLNT each represented a unique digit, and "RBJBR" was a five digit number, what are possible values for the letters? (Or ONE possible value.)
Can we do this in a way that can be done on paper without "guessing and plugging numbers" (or computers, for that matter)?
Got this question as a math challenge from a club, not sure how do go about it.
