The most beautiful word in mathematics: sum

The most unforgettable sentence is: no solution.

The safest word is called; Yes and only

9÷3 "In addition to you, I am still you.

4÷2 "I still love you except you.

1÷ 10 "If I die, my death is meaningless.

I think you are a recurring decimal.

Over and over again, stubborn

I still like you, just like the square of sin plus the square of cos.

Be consistent throughout.

You are the unknown, I am the function.

My heart changes with you.

Life is like an undulating characteristic line.

I'm always on the y axis.

Waiting for you to pass by

Your smile is the "necessary and sufficient condition" for my existence in this world.
