$\huge\text{Hey there!}$

$\mathsf{\dfrac{8(4 - 2^6)}{4}}$

$\mathsf{2^6}\\\mathsf{\rightarrow2\times2\times2\times2\times2\times2}\\\mathsf{\rightarrow 4\times4\times4}\\\mathsf{\rightarrow 16\times4}\\\mathsf{\rightarrow \bf 64}$

$\mathsf{= \dfrac{8(4 - \bf 64)}{4}}$

$\mathsf{4 - 64}\\\mathsf{\rightarrow \bf -60}$

$\mathsf{= \dfrac{8(\bf -60)}{4}}$

$\mathsf{8(-60)}\\\mathsf{\rightarrow \bf -480}$

$\mathsf{= \dfrac{-480}{4}}\\\\\mathsf{\rightarrow \dfrac{-480\div4}{4\div4}}\\\\\mathsf{\rightarrow- \dfrac{\bf 120}{1}}\\\\\mathsf{\rightarrow \bold{-120}\div 1}}\\\\\mathsf{\rightarrow \bf -120}$
