what number can you subtract half from to obtain a result that is zero?

9 Hours and this is all that bit??
Geez..
Ok, ,Well besides being enigmatic, it looks a little ambiguous to boot~!
But I’m a born sucker and love a challenge
So “Alex ill take things only I know for $200 Please”
The answer, if I am reading it properly is ZERO

1/2 :)

It depends on how you look at the question.
If you think of it as "What number can you subtract half (as in 0.5) from..." then it's 0.5 because 0.5-0.5=0
Or...
If you see it as "What number can you subtract half (of its self) from..." then it's 0, because 0-0=0.
So, logically, the answer can be either 0 or 0.5.

my answer would be half itself

easy- zero

not possible

Either 0 or .5
It depends on what you mean.
Are you asking what number you can subtract by taking half of THAT NUMBER to get 0?
Or are you asking what number you can subtract .5 from and get 0?
