The problem is a follows
142 alpha 214 = 331
and
431 beta 123 = 303
where alpha and beta are unknow operators
I am pretty sure they are +,-,*,/
I know the radix (base) must be 5 or higher because 4 is present
By assuming the base to be 5 and converting to decimal, I discover beta = - and the base is indeed five. But if I convert the first part the first part to decimal useing base 5 the answer is wrong.
It is possible I copied the problem incorrectly
In general, my question is, how to determine the base to a number system given a problem similar to the one above.
