Hey there!

-20 ÷ 5 (-3) + 4 (-2) (-1) - 4²

= -4 × -3 + 4 (-2) (-1) - 16

= 12 -8 (-1) - 16

= 12 + 8 - 16

= 20 - 16

= 4.

Hope it helps ya!

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}


\tt \: -20 / 5(-3)+4(-2)(-1)-4 ^ { 2 }

Divide -20 by 5 to get -4.


\tt \: -4\left(-3\right)+4\left(-2\right)\left(-1\right)-4^(2)

Multiply -4 and -3 to get 12.


\tt \: 12+4\left(-2\right)\left(-1\right)-4^(2)

Multiply 4 and -2 to get -8.


\tt \: 12-8\left(-1\right)-4^(2)

Multiply -8 and -1 to get 8.


\tt \: 12+8-4^(2)

Add 12 and 8 to get 20.


\tt \: 20-4^(2)

Calculate 4 to the power of 2 and get 16.


\tt \: 20-16

Subtract 16 from 20 to get 4.


= \boxed{\boxed{ \bf 4}}
