Answer 1

a) Ta có: \(-19-\left|+13\right|+\left|-10\right|-\left(-5\right)-11\)

\(=-19-13+10+5-11\)

\(=-28\)

b) Ta có: \(\left(-10\right)-\left(11\right)+\left|-5\right|-\left|-7\right|-8\)

\(=-10-11+5-7-8\)

\(=-31\)

c) Ta có: \(-\left(-8\right)-\left(+7\right)-\left|-11\right|+\left|+12\right|\)

\(=8-7-11+12\)

\(=2\)

d) Ta có: \(-14-\left|-18\right|-\left(-20\right)-\left|-25\right|\)

\(=-14-18+20-25\)

\(=-37\)

đ) Ta có: \(23-\left|-15\right|-\left(-17\right)+\left|-13\right|\)

\(=23-15+17+13\)

\(=38\)
