operation(s) puzzle

Question

flamebirde    196

If

253=243

512=504

854=837

is true, then what does 689 equal?

Hint: = means "do operation(s) and get x as result" where x equals the answer.

EDIT: the answer was random, I assure you. ;)

Start with ABC. After the operation it is ABC - A - B - C. In other words, add the digits and subtract it from the original number. Therefore 689 = 666
