Do it in super-small steps, each one making it a little simpler. With practice, you may be able to take bigger steps:
-(-6 - (-2)) -(-5)(-8 -1)
-(-1*6 - (-1*2)) -(-5)(-1*8 + -1*1)
-(-1)*(6-2) -(-5)(-1(8+1))
-(-1)*4 -(-5)(-9)
4 - 45
-45 + 4
(-1)*45 + (-1)*(-4)
-1(45-4)
-1(41)
-41

- [ - 6 + 2 ] + 5 (- 9)
4 - 45
- 41
2009-01-01 10:25 pm
-(-6 - (-2)) -(-5)(-8 -1)
=(-(-6 - (-2)) -(-5)(-8 -1))
Closely resolve the brackets
=(-(-6 +2) -(-5)(-8 -1))
=(-(-6 +2) +5(-8 -1))
=(-(-4) +5(-8 -1))
=(-(-4) +5(-9))
=(+4 +5(-9))
=(+4 -45)
=-41 thats your answer HAPPY!

the negative of negative is positive, so...
-(-6 - (-2)) -(-5)(-8 -1) =
-(-6 + 2) -(-5 * -9) =
- (-4) - 45 =
4 - 45 = - 41

that's so basic..

-{-6 - (-2)} - (-5)(-8 - 1)
-(- 6 + 2) - 40 - 5
6 - 2 - 40 - 5
6 - 47
- 41.

First you must remember PEMDAS.
(Step A) -1(-6 - (-2)) = -1(-4) = 4
(Step B) -1(-5)(-8 -1)= (-5)(-9) = 45
(Step C) (4) - (45) = -41

The answer is -41.

(-((-6) - (-2))) - ((-5) * ((-8) - 1)) = -41

-(-6 - (-2)) - (-5)(-8 - 1)
-(-6 + 2) - (-5)(-9)
-(-4) - 45
4 - 45
-41
2009-01-01 10:25 pm
-[-6 - (-2)] - (-5)/(-8 - 1)
= -[-6 + 2] + 5/(-9)
= -[-4] - 5/9
= 4 - 5/9
= 36/4 - 5/9
= 31/9
