Solving rubiks cube in lockdown

My Dad is good at solving rubiks cubes. Sometime I mix the rubiks cubes really well but he can still figure it out. I really want to solve it too.  

Rubik cubes can come in different sizes. We have a 2x2 3x3 4x4  and a dodecahedron one.

I want to learn how to solve 2x2 because my Dad says it is easier and faster.

There are people who are speed cubers and they go into competitions. We like watching them on Youtube. They can solve it in a few seconds. Even children can go into the competition. 

I don't think I can solve it that fast but I still like it. Can you solve it?
