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.

Answer 2

`\huge \boxed{\mathbb{QUESTION} \downarrow}`

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

`\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}}`
