Booze Terms 1~4

(a/b) > 0 when

signs of a and b are the same
| a | = b when

a = b or -a = b
| a | > b when

a > b or a < -b
| a | < b when

-b < a < b
| x | can be rewritten as
- ( x , x >= 0 )
- (-x , x < 0 )
a^3 - b^3 =

( a - b )( a^2 + ab + b^2 )
a^3 + b^3 =

( a + b )(a^2 -ab + b^2)
The slopes of 2 parallel lines are

equal
The slopes of 2 normal lines are

negative reciprocals
The equation of a line with slope m passing through (a,b) is
