Union of sets calculator

1. A = {x<=5; x in N}; B = {2<=x<=8; x in N}; C = {x<=3; x in N}
2. A = {x^2<10; x in N}; B = {x<=1; x in N}; C = {1<=x<5; x in N}
3. A = {1,2,3,4}; B = {3,4,5}; C = {1,3,5}
4. A = {2,3,6}; B = {3,5,6}; U = {1,2,3,4,5,6}
5. A = {x<=9; x in N}; B = {3<=x<=7; x is odd}; C = {1< x<7; x is even}
6. A = {|x^3-2|<=25;x in N}; B = {1< x<5; x in N}; C = {x^4=81;x in N}

Example1. A = {1,2,3,4}, B = {3,4,5}, Find A union B ...
Solution:
Here `A={1,2,3,4},B={3,4,5}`
`A uu B = {1,2,3,4} uu {3,4,5}`
`= {1,2,color{red}{3},color{green}{4}} uu {color{red}{3},color{green}{4},5}`
`= {1,2,3,4,5}`
