Question

If P = { x : -3 < x ≤ 7, x ∈ R} and Q = { x : - 7 ≤ x < 3, x ∈ R} , represent the following solution set on the different number lines: 

P-Q 

Answer 1

P = { x : -3 < x ≤ 7, x ∈ R} and Q = { x : - 7 ≤ x < 3, x ∈ R} 

p = {-2, -1, 0, 1, 2, 3, 4, 5, 6, 7}  and Q = {-7, -6, -5, -4, -3, -2, - 1, 0, 1, 2} 

P-Q = {3,4,5,6,7}
