Sắp xếp theo thứ tự tăng dần:
-(+51) < -l-39l < -37 < 0 < l-18l < -(-19) < 25
Tính:
\(-32+\left\{-54:\left[\left(-23\right)+7.\left|-2\right|\right].\left(-2\right).2\right\}\)
\(=-32+\left\{-54:\left[\left(-23\right)+14\right].\left(-4\right)\right\}\)
\(=-32+\left\{-54:\left(-9\right).\left(-4\right)\right\}\)
\(=-32+\left\{6.\left(-4\right)\right\}\)
\(=-32+\left(-24\right)=-56\)
