Int value only decreasing once

Question

if my code is this:

health = health - 5

and my base health is 50 then however manytimes i cout "health" its still 45 why

Answer 1

If you only perform the operation once, five will be substracted only one time. Thus, it is correct that 'health' is 45.
The Variable health = The value of health - 5
-> health = 50-5
health is 45
and will not change anymore until you want it to.

Answer 2

yes but i subtract it twice in the same code and it is stil saying that it is 45

Answer 3

can you schow us the code then?
