Math Help Needed!!!! Really Easy!!! 10 Points!!

[From: ] [author: ] [Date: 11-12-16] [Hit: ]
Multiply -1 by the -1 inside the parentheses.Subtract 27 from 5 to get -22.Add 1 to -22 to get -21.-21-5+3(-2-7)-(-2+1) - Multiply 3 by what is in the parenthesis.5 plus multiply 3X-2 plus multiply 3X-7 plus minus minus 1.5 + - 27 + 1 = + 6 - 27 = - 21-The rules are to do the stuff in parentheses first,......
It would be great if someone could help me out with this problem and explain how did it. Thanks in advance.

5+3(-2-7)-(-2+1)

Hope this helps

5+3(-2-7)-(-2+1)

Subtract 7 from -2 to get -9.
5+3(-9)-(-2+1)

Add 1 to -2 to get -1.
5+3(-9)-(-1)

Multiply 3 by each term inside the parentheses.
5-27-(-1)

Multiply -1 by the -1 inside the parentheses.
5-27+1

Subtract 27 from 5 to get -22.
-22+1

Add 1 to -22 to get -21.
-21

-
5+3(-2-7)-(-2+1) - Multiply 3 by what is in the parenthesis.
5+(-6)-21-(-2+1) - -2+1 is -1
5+(-6)-21-(-1) - 5+(-6) is -1
-1-21-(-1) - -1-21 is -22
-22-(-1) - 2 Negatives = a positive
-22 +1
-21

-
5+3(-2-7)-(-2+1)
5 plus multiply 3X-2 plus multiply 3X-7 plus minus minus 1. (minum minus 1 is plus 1)
5-6-21+1
6-27 combine pluses and minuses
ans: -21

-
5 + 3 times (- 2 - 7 ) - ( - 2 + 1)

3 times ( - 2 - 7 ) = 3 ( - 9 ) = - 27

- ( - 2 + 1 ) = - ( - 1 ) = + 1

5 + - 27 + 1 = + 6 - 27 = - 21

-
The rules are to do the stuff in parentheses first, then multiplication, then addition/subtraction.

PEMDAS
-2-7=-9
5+3*-9-(-2+1)
-2+1=-1
5+3*-9-(-1)
3*-9=-27
5+-27-(-1)
5+-27=-22
-22-(-1)=-23
-23

=-19
