The answer in number 2 is CORRECT

but

The Answer in number 1 is TOTALLY WRONG

--

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

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

36-4+3-15

36-1-15

35-15

20

1+5*7-4+9/3-(6+7-8)*3 = 20

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

36 - 1 - 15 and finally the subtraction

20

-4+3 = -1, not -7

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

1+5*7-4+9/3-5*3          multiply/divide

39-19

= 20

#2. 5-13-8/2-61+5          divide

10-78

= -68
