In Step 1 and the final step to solve the 1x1, you use a algorithm, that algorithm is U Ui.
There's not a specific amount, but if you haven't learned yet, you may not know that there are methods to solving the Rubik's Cube (obviously, since people can solve them in 7 seconds). All Rubik's Cube methods involve algorithms. All an algorithm is is a series of moves that you do to accomplish something on the cube. For example, "R U R' U R 2U" is an algorithm. Although there isn't a set number of moves to solve a Rubik's Cube because of how many possibilities you can get from scrambling, there are, however, only 7-9 algorithms that one must memorize to solve the Rubik's Cube. That's only the beginner method, whereas in more advanced methods you could learn 70+ algorithms to solve the cube. The advanced methods help one to accomplish layers of the cube faster so as to decrease solve time.
M = Turning the Middle layer towards you. M' = Turns the layer away from you
You can get a Rubik's cube in the nearest Toys R Us shop, or you could order one from an online store such as Amazon.

Because it's a cube and it was created by Erno Rubik.
The Rubik's Cube was invented by a Hungarian named Ernő Rubik in 1974. It's originally name was the Magic Cube but changed to the Rubik's Cube in 1980.

Such an algorithm is called a 'God algorithm', from the fact that it would only be known by god/the gods. Although many have tried to find it, none have so far discovered it (assuming it exists). To solve a cube by algorithm, you need to know the appropriate algorithm to apply and when in the stages of solving; different sets can use large numbers of algorithm.
Rubik's Cube was created in 1974.
Yes. Rubik's Cube competitions are fairly popular among Rubik's Cube solvers.
