| - 11/3| + ( - 1/2)^2 - | 4/1/2 + ( - 3,25)|

Lời giải:

\(\left| {\frac{{ - 11}}{3}} \right| + {\left( {\frac{{ - 1}}{2}} \right)^2} - \left| {4\frac{1}{2} + ( - 3,25)} \right|\)

\( = \frac{{11}}{3} + \frac{1}{4} - \left| {4,5 - 3,25} \right|\)

\( = \frac{{11}}{3} + 0,25 - |1,25|\)

\( = 0,25 - 1,25 + \frac{{11}}{3}\)

\( = - 1 + \frac{{11}}{3} = \frac{8}{3}\).
