conditional statements

original:
"If I stay up on Netflix all night then I won't be able to stay awake at school the next day"

inverse:
"If I don't stay up on Netflix all night then I will be able to stay awake at school the next day"
This isn't true because I could be staying up all night not on Netflix, maybe studying or reading, and still not be able to stay awake the next day.

converse:
"If I am not able to stay awake at school the next day then I stayed up on Netflix all night"
This isn't true for the same reason inverse isn't true, I could've stayed up doing other things or I could've just not had a good night of sleep.

contrapositive:
"If I am able to stay awake at school then I didn't stay up on Netflix all night"
This statement is true because I was able to stay awake at school so that means I didn't stay up on Netflix all night.

Why I Like Math..

Most people don't enjoy doing math, and admittingly I am one of those people. But one of the reasons I do like math, is that it applies to things that I do enjoy doing. If I didn't know math, things that I do enjoy to do would be a lot harder. I couldn't cook because I wouldn't be able to get correct measurements in recipes. I wouldn't be able to play field hockey and lacrosse if I couldn't estimate shooter's angles when they take shots on me.  So I don't really dislike math. I dislike the idea of sitting down at a desk and mindlessly doing problems that don't mean anything to me. But when I use math in real life, it is helpful and I couldn't get along as well if I didn't.
