conditional statements

1. Original: if you put on sunscreen, then you won't get a sunburn.

2. Inverse: if you don't put on sunscreen, then you will get a sunburn.

3. Converse: If you didn't get a sunburn, then you put on sunscreen.

4. Contrapositive: If you get a sunburn, then you didn't put on sunscreen.

The original is true (obviously). The inverse and converse are not true because some people don't burn or don't need to wear sunscreen, so if you don't put on sunscreen you might not get a sunburn and if you didn't get a sunburn you still might not have put on sunscreen. The contrapositive is true because in the first statement I said that if you put on sunscreen you will not get a sunburn. So, based on those conditions, if you get a sunburn you didn't put on sunscreen.

why I like math

As a j&c major, math isn't really my forté. But there are reasons why I like it, one of them being that there usually isn't much writing involved (okay just because im in j&c doesnt mean I like to write, and essays get boring). So there's that, and then there's also the fact that math is one of the few subjects that we'll actually need in real life. I mean the next time you need to know a political fallacy or the different chinese dynasties, let me know. But math is everywhere, you need basic math skills to do tons of things and although I wish you didnt need to be at least halfway good at math to succeed, you do.
