Correct me if I am wrong.....
R denotes a set of all real numbers
Z denotes a set of all integers
Z+ denotes a set of all positive integers
A={ x ∈ Z+ l -a < x ≤ b}
B={ x ∈ R l -a ≤ x < b}
C={ x ∈ Z l -a ≤ x < b}
Given that a = 5 and b = 7. Find the answers to thesequestions.
1. A, A = {0,1,2,3,4,5,6,7}
2. B, B = {-5,7}
3. C, C = {-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}
4. BC (I need help with this, I don'tunderstand)
5. B - A = {-5}
