Decide all proper subsets of A { 8 ,7 ,6 ,5 ,4 ,3 ,2 ,1} = A 1- { 4 ,3 ,2 ,1} 2- { } 3- { 9 ,8 ,7 } 4- { 11 ,2} 5- { 5 }

Answer:
A, E
Step-by-step explanation:
There should be 2^8-1 proper subsets of A. Its every one besides { }
Around an 80 percent depending on how much those test are worth towards your grade

A is answer
Answer:
If these are addition:
1) 7
2) 3
3) 1
4) -3
5) 0
6) -5
If they are subtraction:
1) 9
2) 9
3) -7
4) 7
5) -4
6) 3
Step-by-step explanation:
Difference is subtraction, but your examples (7 and -3 = 10) implies that these are addition problems. Next time please set them up in a mathematical form.
This is how the problems would be set up:
Addition:
1) 8+(-1)= 7
2)6+(-3)= 3
3)-3+4= 1
4)2+(-5)= -3
4)-2+(-2)= 0
6)-1+(-4)= -5
Subtraction:
1) 8-(-1)= 9
2)6-(-3)= 9
3)-3-4=- 7
4)2-(-5)= 7
4)-2-(-2)= -4
6)-1-(-4)= 3
The second question is biased
