1, add 52.8 to any number, multiply it by 5, subtract the difference from 3.9343, divide it by 0.5, subtract ten times this arbitrary number and add 1.1314, and the result is always equal to 521. [(n+52.8) × 5-3.9343] ÷ 0.5-10× n+1= 521.1314, where n is any real number.

Our hearts are a circle, because their eccentricity is always zero. My yearning for you is a recurring decimal, which is stubborn over and over again.

We are parabola, you are the focus, and I am a straight line. I miss you as much as you think I am.

4. A zero vector can have many directions, but only one length. Just like me, I can have many friends, but there is only one you, which deserves my protection.

5. Life can be sweet or bitter, but it can't be without you; Just as the denominator can be positive or negative, it can't be meaningless and the value is zero.

6. With you, my world is infinite, because there are no real numbers to express. I love you deeply.

7. My feelings for you are like an exponential function based on the natural constant E. No matter how many storms I have experienced, my true feelings will remain unchanged.
