New to this boolean stuff. Can anyone tell me if these look correct. Thanks for helping me learn.


!(x<5) && !(y >=7)
!(x<5) && !(y >=7)
x>5 && y<7


and also,


!(a==b) || !(g !=5)
a!=b || g==5

Thanks,
John

Both are correct.

From above,

!(x<5) && !(y >=7)
x>5 && y<7

Shouldn't the final result be as follows?

x>=5 && y<7

(Considering the case where x=5.)

Oops! Missed that one, indeed you must take account of the condition where x=5 as alhirzel has pointed out.
