The Funny Calculator

A calculator has these buttons:





Just like a “normal” calculator,  

When you type 1 x 10, it says 10.
When you type 1 + 10, it says 11.

But…

When you type 1 + 1, it says 10.
When you type 10 + 10, it says 100.

--------------------------------------------------------------------------------------------

Using this information alone:

How would you count from one to four?  

What would the calculator say if you typed in 100 10 ?
    

Extending the pattern:


 Can you extend the pattern to count up to twenty?

What would the calculator say if you typed in 0.1 + 0.1?

What would the calculator say if you typed in 0.1 x 10 ?

What would the calculator say if you typed in 111 + 111 ?

What would the calculator say if you typed in 111 x 10 ?
