Answer 1

1.[6+8(8/4)]-6
= [6+8(2)] - 6
= [6+16]-6
= 22-6
= 16 [Answer]

2. -7(2-(-1)-(-3)(4-9)
The expression is erroneous.
*** I dont know how some of you got the answer. If you guys are confused, at least dont give wrong answers. Because, see the brackets, its wrongly presented. There should always be even no. of brackets. But here, there is 7 including starting and closing brackets.

3. -8-2(-3)
= -8+6
= -2 [Answer]

4. 7-(-6)(-4)
= 7-(24)
= 7-24
= -17 [Answer]

5. -(-2)-4(3-2)
= 2-4(1)
= 2-4
= -2 [Answer]

6. [5+16(24/8)]
= [5+16(3)]
= [5+48]
= 53 [Answer]

7. 8(-1-3)-(-7)(-5-4)
= 8(-4)+7(-9)
= -32-63
= -95 [Answer]

8. -(4)-6(6-5)
= -4-6(1)
= -4-6
= -10 [Answer]

9. -5-(-2)(6)
= -5+12
= 7 [Answer]

10. -(-7)-5(8-3)
= 7-5(5)
= 7-25
= -18 [Answer]

11. -5(5+9)-1(9-7)
= -5(14)-1(2)
= -70-2
= -72 [Answer]

Answer 7

Try this....

Order of Operations:
Please (Parenthesis)
Excuse (Exponets)
My (Multiplication)
Dear (Division)
Aunt (Addition)
S (Subtraction)

1. 16
2. 84
3. -2
4. -17
5. -2
6. 53

Try the rest of the problems.....a negative times a negative equals a positive and a ()() means times. If you times two negatives then you get a positive but if you do a negative and a positive then you get a negative.

If all else fails try using a calculator..

Hope this helps!
