The problem is a follows(adsbygoogle = window.adsbygoogle || []).push({});

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 similiar to the one above.
