For problem #1 the answer should be 20.

#1. 1+5*7-4+9/3-(6+7-8)*3 take care of parenthesis

1+5*7-4+9/3- 5*3  Do the multiplication

1+35-4+9/3- 15   do the division

1+35-4+3- 15  now the addition

36 - 1 - 15 and finally the subtraction

20



-4+3 = -1, not -7

   1+35-4+3-15          add/subtract

   39-19

   = 20



#2. 5-13-8/2-61+5          divide

   5-13-4-61+5          add/subtract
