ALL the elements in set A combined with all the elements in set B.Example:When A={1,2,3,4} and B={2,3,6} The union of Sets A and B would be: {1,2,3,4,6} , because both sets contain those numbers.
Union.
The (operation) union in mathematics usually refers to sets of numbers and means the combination of those sets. The best way to describe it is to use an example: Take some set A with the numbers 1, 2, 3, 4, 5 in it and some set B with the numbers 1, 3, 5, 7, 9 in it. The union of these two sets would be the list of all things (list of elements) that is in EITHER set. As long as something is in one of the sets, it's in the union of the sets. Going with the example, the union of these two sets would be 1, 2, 3, 4, 5, 7, 9. Note though that you do NOT count something twice if it's in both sets, it's only counted once.
A = { 0 } B = { 0, 1 } Or, in fact, any set would would, as long as A = B. Or A = an empty set.
If 10% of the voters took an oath of allegiance, the state would berestored to the Union.

Many US Civil War historians have explored the question as to why the Union did not focus many forces, both naval and army concentrations on the Atlantic coastlines of the Confederacy. After the failed Peninsula campaign in 1862, the Union paid more attention to the West and even more attention on Virginia, especially north of Richmond. A good number of historians have pointed out that Union concentrations against the East coast would have brought a rapid response from the Confederates. The Rebels were hyper-sensitive to the eastern railroads that supplied Virginia and Richmond. These same railroads would be used by the Rebels to facilitate troop movements to areas where they were needed the most. Based on the manner in which the Union used its armies, a focused effort on the eastern coastlines would have diverted their troops from other places such as the West and northern Virginia. Also, the Union would need to used combined naval and army forces to make serious incursions on the east coast. In such situations, the South would have an advantage because of their communication lines. All the main ports had telegraph lines whereas the Union's troop transports would not be able to communicate with each other. In summary, Union activities on the Southern Atlantic coastlines would bring a rapid response to meet Federal challenges which would have lacked good means of communications, not to mention that Union supply lines would have been more than difficult to create and protect.
The reason the capturing of the Confederacy capital in Richmond was so difficult for the Union to accomplish was because it was so well guarded. The Confederate Army, protected it because they felt the Confederacy would fall if Richmond fell.
Most slave states left the union. The "border" states that practiced slavery, but stayed in the union, probably realized it would be too difficult to fight off the North.
Many slaves escaped to the north during the American Civil War. If captured by the south, the runaway could have ears cut off, or be hamstrung, or branded, and taken back south. For many, the goal of safety and freedom was too great to ignore.
These are a few military strategies the Unions and Confederates had:nion (North): formed lines to prevent Confederate forces from passing into Union campsConfederate (South): charged uphill to Union lines

Yes. After the Union army defeated the Southern soldiers in battles, many blacks left the places where they were kept as slaves and went over to the Union lines, showing the Union soldiers places in the nearby area that might help them to win the war. Many former black slaves joined General William T. Sherman's army as he marched through the south from Georgia, to South and North Carolina.
Many salt production locations were inland from a waterway. The Union would dock and send a raiding party to destroy Confederate salt locations. The problem the Union faced was that the kettles used in producing salt were too heavy to be carried away. Also, they were difficult to destroy because the metal kettles often were from one to three inches thick.
