\(|-7|+|-14|=7+14=21\).
\(\left|\frac34\right|+\left|-\frac34\right|=\frac34+\frac34=\frac32\).
\(|-20|+\left|-\frac56\right|=20+\frac56=20\frac56\).
\(|1.7|-\left|-\frac15\right|=1.7-0.2=1.5\).
\(\left|-6\frac12\right|+\left|2\frac34\right|=6\frac12+2\frac34=9\frac14\).
\(24.4-|-12|-|-3|=24.4-12-3=9.4\).
\(|-3.1|\cdot|-4.1|=3.1\cdot4.1=12.71\).
\(|-0.6|\cdot\left|3\frac13\right|=0.6\cdot\frac{10}{3}=2\).
\(|-0.45|:|-0.9|=0.45:0.9=0.5\).
\(|-12|:|-3|=12:3=4\).
\(|-5.4|+|1.8|:|0.4|=5.4+1.8:0.4=5.4+4.5=9.9\).
\(13.2\cdot(5-|-2|)=13.2\cdot(5-2)=39.6\).
\(7\frac12:(|-7|+|-8|)=7.5:(7+8)=7.5:15=0.5\).
