A = { 1 , 2 , 3 , 4 , 5 }
B = { 2 , 4 , 6 , 8 , 10 }
<u>Finding </u><u>A</u><u> </u><u>union</u><u> </u><u>B</u><u> </u><u>(</u><u> </u><u>A</u><u> </u><u>∪</u><u> </u><u>B</u><u> </u><u>)</u>
<u>The</u><u> </u><u>union</u><u> </u><u>of </u><u>sets</u><u> </u><u>A</u><u> </u><u>and</u><u> </u><u>B</u><u> </u><u>is </u><u>the </u><u>set </u><u>of </u><u>all</u><u> </u><u>elements</u><u> </u><u>which</u><u> </u><u>belongs</u><u> </u><u>either</u><u> </u><u>A</u><u> </u><u>or </u><u>B</u><u> </u><u>or</u><u> </u><u>both</u><u> </u><u>A</u><u> </u><u>and</u><u> </u><u>B</u>
