$\\ \rm\Rrightarrow -8=2(-4)=-8\checkmark$

$\\ \rm\Rrightarrow -12=-4-3\implies -12\neq -7$

$\\ \rm\Rrightarrow -12=-4-4-4\checkmark$

$\\ \rm\Rrightarrow \dfrac{-4}{4}=-1\checkmark$

$\\ \rm\Rrightarrow -4+4=0\neq 8$

$\\ \rm\Rrightarrow (-4)^2=16\neq -16$

$\\ \rm\Rrightarrow 15(-4)=-60\neq 60$

$\\ \rm\Rrightarrow -4=60.50\implies -4\neq 3000$

$\\ \rm\Rrightarrow -4\neq \dfrac{60}{15}$
