33333-4

If you meant 33333 − 4, the result is 33329.

Reason: subtract 4 from the units place; borrow from the tens place, giving 13 − 4 = 9, and the rest digits stay the same, so 33329.

If you meant something different (e.g., a pattern, base, or a larger problem), please share more context. Would you like more practice problems like this?
