I’m not a phone but I got a lot of buttons. And and screen , i can fit well in your hand. I’m shaped in different colours and size. And i can promise you that I’m pretty good at Maths. I’m used since the old ages. I am a CALCULATOR.
My favourite person is Albert Einstein because beside most of the people he really likes maths and physics, I don’t have to many friends, but I was his best friend for a long time. Also, I were able to help him in all his discovers and theories.
