This question was answered in a heartbeat by others but I'll still post the solution anyway. Will try to get more difficult questions in the future that are less likely to be answered.

1) [math]\frac{1}{4}-12 = \frac{1}{4} - \frac{48}{4}= \frac{-47}{4}[/math]

2) [math]-18+(-12)=-18-12=-30[/math]

3) [math]x + 29[/math] given $x=-15$. [math]-15+29=29-15=14[/math]

4) [math] \frac{-3}{4}- \frac{-1}{4}= \frac{-3}{4}+\frac{1}{4}=\frac{-2}{4}= - \frac{1}{2}[/math]
