Answer 1

$\Large\displaystyle\begin{gathered} \sf{ -1-(-5)\cdot(-3)+(-4)\cdot3:(-4)} \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{-1+5\cdot(-3)+(-4)\cdot3:(-4) } \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{ -1+5\cdot(-3)+1\cdot3} \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{-1-15+3 } \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{-16+3 } \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{ -13}}} \end{gathered} }$
