`1 +2 [(3-5)2 - 8]= 1+ 2[(-2)2-8] = 1 +2[-4-8] = 1+2[-12] = 1-24 = -23`

Answer 2

Hello!

Step-by-step explanation:

This question's it's about the order of operations. It stands for parenthesis, exponents, multiply, divide, add, and subtract. It can also go left to right.

Do parenthesis first.

`1+2=3`

`(3-5)*2-8`

`-2*2-8`

Multiply left too right.

`-2*2=-4`

`-4-8`

`=-12`

Add/subtract left too right.

`1+2(-12)`

Multiply left to right.

`2(-12)=-24`

`1-24=-23`

Answer:
`\boxed{=-23}`

Hope this helps!
