0/10 Bad puzzle, didn’t prevent the infinite amount of alternate solutions
t=0+8073 works (try substituting yourself, the 0 gets pasted onto other numbers) s=-12 works B=1.5* works etc.
W can be -168121+2
(no spoilers: these are all solutions that are strictly* correct but don’t give the right final answer)
I got -72958 from entirely strictly* valid substitutions.
*strictly means that stuff like (2)5 = 10 and 055 = 55 are NOT allowed.
