Answer 2

-188

Explanation:

when it has ( ) , we do ( ) inside first;

inside the ( ), if it has addition, subtraction , multiplication and division,

we always do multiplication and division first ,then do addition and subtraction.

if without ( ) , we still do multiplication and division first ,then do addition and subtraction.

(9-84÷2×5+5+6)+2

it has ( ) ,so we do ( ) first , and inside the ( ) , it has addition, subtraction , multiplication and division, we do "84÷2×5" first,

so it is : (9-42X5+5+6)+2=(9-210+5+6)+2

now it has ( ) and +

we do ( ) first

inside the ( ) , it has - +

we just do them one by one

it is -190+2=-188
