$(-4)\times(-9)\div3\times2$(答案不唯一)
$\{3,2.012,1\frac{1}{4},-(-2.28),2.\dot{1}0\dot{1},\cdots\}$
$\{3,0,-2^{16},-|-4|,\cdots\}$
$\{-2.4,-\frac{10}{3},-0.15,\cdots\}$
$\{3,2.012,1\frac{1}{4},0,-(-2.28),2.\dot{1}0\dot{1},\cdots\}$
解$:$原式$=4.6-1.6+4+\frac {3}{4}-\frac {3}{4}$ $=7+0$ $= 7$
解$:$原式$=\frac {1}{5}×(-60)-\frac {1}{2}×(-60)-\frac {5}{12}×(-60)$ $=-12+30+25$ $= 43$
解$:$原式$=-\frac {3}{2}×(3×\frac {9}{4}-1)$ $=-\frac {3}{2}×\frac {23}{4}$ $= -\frac {69}{8}$
解$:$原式$=-27×2-[\frac {25}{27}-(1-\frac {1}{5}×\frac {5}{3})×(-\frac {1}{9})]$ $=-54-[\frac {25}{27}-\frac {2}{3}×(-\frac {1}{9})]$ $=-54-1$ $= -55$
