Answer 1

`(16-8)*2+4`

Explanation:

If we use PEMDAS we can find out which equations is equal to 20

⇒ 1st Option:

`(16-8)*2+4`

Do what is is parenthesis first

`8*2+4`

Multiply next

`16+4`

Add them together

`20`

⇒ 2nd Option:

`(16-8)*(2+4)`

Do what is in the parenthesis first

`8*6`

Multiply

`48`

⇒ 3rd Option

`16-8*(2+4)`

Do what is inside the parenthesis first

`16-8*6`

Multiply

`16-48`

Subtract

`-32`

⇒ 4th Option

`16-(8*2+4)`

Multiply what is inside the parenthesis first

`16-(16+4)`

Add what's inside the parenthesis

`16-20`

Subtract

`-4`

Since only the first option equals 20 then the first option is the only correct option
