pragma solidity ^0.5.7;

    contract Test {
        function test() public view  returns (uint){
             return 10*10;
        }

        function test2() external view  returns (uint){
             return 10*2;
        }
    }

1) according to my knowledge external means we cannot call the function inside class but how i am able to call it ?

Can any one please explain? This is my output which i can see in remix console.

Sure you can: this.test2() instead of just test2. But notice that msg.sender will be changed to this.

public = internal + external
