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


\\ \rm\Rrightarrow -12=-4-3\implies -12\\eq -7


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


\\ \rm\Rrightarrow (-4)/(4)=-1\checkmark


\\ \rm\Rrightarrow -4+4=0\\eq 8


\\ \rm\Rrightarrow (-4)^2=16\\eq -16


\\ \rm\Rrightarrow 15(-4)=-60\\eq 60


\\ \rm\Rrightarrow -4=60.50\implies -4\\eq 3000


\\ \rm\Rrightarrow -4\\eq (60)/(15)
