T&T PI U8 Re

My original smartphone has some special apps.
I’ll tell you about two of them.

I have a math app for fun.
I like math apps because they’re exciting.
It’s fun to learn with an app.
I have a quiz game for studying.
I need it because I like think.
I need it because I’m not good at Japanese

Of course, these apps use programming.
Programming is useful.

I learned how to move a rocket.
The rocket moves according to my programming.
Where will I send it?
