128√e986 is defined as wiping about half the top, and I love you if you don't wipe E.

For example:

1, (528× 0.5-3.9343) ÷ 0.5 = 520.1314, I love it all my life.

2,250 x 2+38-17.8686 = 520.1314, I love it all my life.

3. [(n+52.8) × 5–3.9343] ÷ 0.5-/kloc-0 × n = 520.1314 (n = any number), I love it all my life.

4.r=a( 1-sinθ), r=a( 1-cosθ) or r = a (1+cos θ) (a >: 0) in the horizontal direction. Heart line.

The origin of mathematical formula:

Modern people don't write love letters, but use romantic mathematical formulas. The mathematical formula of I love you comes from a MV by Korean singer Kwill, named "I Need You".

The girl wrote a mathematical formula "128 radical e980" on the blackboard for the hero to answer, but the hero couldn't figure it out after thinking hard, so the girl picked up a brush and erased the upper part of the formula, which became English I Love You.
