saw these 3 equations in a tv triller and found them very interesting.
science - ethics = murder
life - dreams = jobs
emotions - logic = faith

allegedly, scientists sacrifice human lives in the name of science for advanced medical research. this's definitely a controversial topic.
80% of world's population hates their jobs. it is their dreams that keep them going.
there is a constant struggle between logic and faith as the latter is belief not based on proof

mathematically, they can also be:
science = murder + ethics
life = jobs + dreams
emotions = faith + logic

..and similarly, the following:
ethics = science - murder
dreams = life - jobs
logic = emotions - faith

all of them just make sense, needless for me to explain right.
