If you multiply or divide by a positive number, you do not switch the sign.
2x+%3E+2
x+%3E+1
If you add or subtract by a negative or positive number, you do not switch the sign.
x+%2B+1+%3E+1
x+%3E+0
and
x+-+1+%3E+1
x+%3E+2
If you divide or multiply by a negative number, you switch the sign.
-x+%3C+4

whats the rule for switching the sign?
----------------
A fraction has three signs:
1. the sign of the fraction
2. the sign of the numerator
3. the sign of the denominator
RULE: Any two of the signs may be changed without changing
the value of the fraction.
