= - 6 - (- 2) + (- 7) - 11
= - 17 + 2 - 7
= - 22
Answer: - 22
= - 17 + 2 - 7
= - 22
Answer: - 22
2009-07-08 10:40 pm
= -6 + 2 - 7 -11
= -4 - 7 - 11
= -4 + (-7) + (-11)
= -22
= -4 - 7 - 11
= -4 + (-7) + (-11)
= -22

-22
-6-(-2) = -4
-4 +(-7) = -11
-11-11 = -22
-6-(-2) = -4
-4 +(-7) = -11
-11-11 = -22

-22
-6 - (-2) = -4 * look at the 2 minus signs and make them a positive sign.
-4 + -7 = -11
-11 - 11 = -22
-6 - (-2) = -4 * look at the 2 minus signs and make them a positive sign.
-4 + -7 = -11
-11 - 11 = -22
2009-07-08 11:30 pm
-6 - (-2) + (-7) - 11
= -6 + 2 - 7 - 11
= -4 - 7 - 11
= -11 - 11
= -22
= -6 + 2 - 7 - 11
= -4 - 7 - 11
= -11 - 11
= -22

Here is one way to do it:
-6+2-7-11 = 2 + (-6-7-11) = 2 + (-24) = 2 - 24 = -22
Here is another
-6+2-7-11 = - 4 - 7 - 11 = -22.
Most people abuse notation and use only one kind of "minus sign". If you are going to use two signs, "-" for "unary minus", and "–" for "binary minus" then you can simplify using some of these facts:
0 – b = -b
-(-b) = b
a – b = a + (-b)
a – (-b) = a + b
-(a+b) = (-a) + (-b)
-(a – b) = (-a) + b
-a = (-1)(a)
Also, exponentiation has higher priority than unary minus, so for example: -4² means -(4²) = -16. If you wish to indicate the square of -4, you have to use parentheses: (-4)² = 16.
-6+2-7-11 = 2 + (-6-7-11) = 2 + (-24) = 2 - 24 = -22
