The answer in number 2 is CORRECT

but

The Answer in number 1 is TOTALLY WRONG

--

this is the correct ANSWER

#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

1+35-4+3- 15 now the addition

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

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

10-78

= -68

I can answer questions in basic algebra and any grade school math.

Love math, currently helping my nephew get through Intermediate Algebra.**Education/Credentials**

I majored in Math Ed in college (but decided not to teach), so have over 40 credits of math.
