Subtract:

$-11$ from $-6$

$-4$ from $12$

$\left|-5\right|+\left|5\right|$

$-\left|5\right|+\left|5\right|$

${\left(-5\right)}^6$

${\left(-3\right)}^2\times {\left(-2\right)}^2\times {\left(-1\right)}^3$

${\left(-4\right)}^2\times {\left(10\right)}^4$

${\left(-1\right)}^{27}\times {\left(-1\right)}^{53}\times {\left(-1\right)}^4$

$5\times \left[25+\left\{\left(-4\right)\times \left(16-8÷2\right)\right\}\right]$
