Standard Form
- For numbers: in Britain it means "Scientific Notation", in other countries it means "Expanded Form" (such as 125 = 100+20+5)
- For a line it means the form: Ax + By = C
- For equations it means the form: (some expression) = 0
- For a quadratic equation it means the form: ax2 + bx + c
