- 1,5 + 2. | 2/1/2| - 6.| - 16/3| + 5.| - 0,3

Lời giải:

\(( - 1,5) + 2\,\,.\,\,\left| {2\frac{1}{2}} \right| - 6\,\,.\,\,\left| {\frac{{ - 16}}{3}} \right| + 5\,\,.\,\,| - 0,3|\).

\( = ( - 1,5) + 2\,\,.\,\,\frac{5}{2} - 6\,\,.\,\,\frac{{16}}{3} + 5\,\,.\,\,0,3\)

= −1,5 + 5 – 32 + 1,5

= (−1,5 + 1,5) + (5 – 32)

= 0 – 27 = – 27.
