Bad Examples of Mathematical Writing

Mathematical Writing Is Not Simply to Use Mathematical Notations and Symbols as Much as Possible and List Mathematical Formulas

   2y2 = 2x2 + 4x + 2 = 2 (x + 1)2 / 2 = (x + 1)2
= y = x + 1

Used the mathematical symbol "=" incorrectly and inconsistently

    x4 + 1 = 2x2
= x4 - 2x2 + 1 = 0
= (x2 - 1)2 = 0
= x2 - 1 = 0
= x2 = 1
= x = 1, -1

Do not use the equals sign "=" for representing logical relationships
