2) explains, what operations and with what operators You can do

3) asks You to print Your first number, operator and (in some cases) second

number of Your calculation

##### Important: when You want radical(root), logarithm or exponentiation You should type Your operator as it was shown in the list and instead of "i" print there index You want

4) (optional) shows You Your mistakes and asks to correct them

5) prints You the result of Your calculation

6) asks if You want to exit the Calculator or continue calculating.
