Answer 1

\(a,\left|75\right|:\left|-5\right|=75:5=15\)

\(b,\left|2\right|.\left|-3\right|.\left|-4\right|+\left|-11\right|=2.3.4+11=35\)

\(c,\left|-11\right|+\left|-12\right|-\left|-17\right|+\left|9\right|=11+12-17+9=15\)

\(d,\left|35\right|:\left|-7\right|.\left|-2\right|+\left|17\right|=35:7.2+17=27\)

\(e,\left|25-14\right|.\left|-3\right|+\left|-7\right|=11.3+7=40\)
