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}
