please help me in this problem:(integers)
evaluate each expression.

1. Do all operations according to "PEMDAS".

2. Do ONLY ONE operation at a time and copy
everything else over:

3. Get the numerator down to one number before
starting on the denominator.

 1) 

-3{2(15-5)-(-7-8)}
-3{2(10)-(-7-8)}
-3{2(10)-(-15)}
-3{20-(-15)}
-3{20+15}
-3{35}
-105


 2) 

{4(-11-7)+9}+5(5-9)
{4(-18)+9}+5(5-9)
{-72+9}+5(5-9)
{-63}+5(5-9)
{-63}+5(-4)
{-63}+(-20)
-83

 3) 
{41-7(9-4)}-{3(9)-1}
{41-7(5)}-{3(9)-1}
{41-35}-{3(9)-1}
{6}-{3(9)-1}
{6}-{27-1}
{6}-{26}
-20


 4) 
2{-5+3(4-5)}
-------------
    -4

2{-5+3(-1)}
-----------
    -4

2{-5-3}
--------
   -4

2{-8}

 5)
 
6{2-(-6+2)}+20
----------------
    2(5-6)

6{2-(-4)}+20
-------------
    2(5-6)

6{2+4}+20
----------
  2(5-6)

6{6}+20
--------
 2(5-6)

 6)
 
9+3{5-6(1+4)}
-------------
  3+8(7-6)

9+3{5-6(5)}
------------
  3+8(7-6)

9+3{5-30}
----------
 3+8(7-6)

9+3{-25}
--------
3+8(7-6)

9+{-75}

 4(5)+6-6{3-3(4)}
------------------
    1-3(5-2)

 4(5)+6-6{3-12}
----------------
    1-3(5-2)

 4(5)+6-6{-9}
----------------
    1-3(5-2)

 20+6-6{-9}
------------
  1-3(5-2)

 20+6+54
---------
1-3(5-2)

 26+54
---------
1-3(5-2)

 8) 4(-2+7)-7{5-(7+4)}
     4(5)-7{5-(7+4)}
     4(5)-7{5-11}
     4(5)-7{-6}
     20-7(-6)
     20+42
     62
