To the first set how need make (press hearth and favorite [let's make 10 hearths and 10 favorites] I make the version 2.1. In 2.1. version, radical will be a new operation.) . The next step is say the x, y, and z. For example, you press ''+''. The situation is this: x+y=z Always, the ''z'' is the result at the simple operations. at hard operations (radical), the result is y.
