Hmm...I got 1, but maybe I just didn't understand how you wrote it...

I think that you are supposed to start with the 3 squared which equals 9, and then subtract 11-9=2.

Then:

19-3[2+2(2)] , and 2+2(2)=6, so

19-3(6)

19-18=

1

ok.. so. so start off by going from left to right, just like how we read.

this is the order you need to know-- the order of mathematics

P-arenthesis

E-xponents

M-uliplication

D-ivision

A-ddition

S-ubtraction

Multiplication and Division are on the same level of importance

Addition and Subtraction are on the same level of importance.

it depends which one is further left (bc it's like reading a book, left to right)

19-3=15, so it's

15[ 2+2(11-3 power of 2)]

THEN- we see that there's an exponent

the exponent (2) only applies to (-3), so -3 squared= +9

now we have :15[2+2(11+9)]

do the math in the parenthesis first:

15[ 2+2(20)]

then multply: 15[2+40]

now add what's in the parenthesis: 15(42)

now multiply: 630
