When I was in high school, a friend of mine gave me a laptop.
She said it had an Internet connection and a keyboard, so it could be used to do the things I wanted to do.
I decided I was going to use it to do my math homework.
I wanted the calculator to display the correct answer for each question, but it wasn’t displaying any data.
That’s when I realized that this was not a laptop that was going anywhere, and that it could, in fact, be useful.
I made it my first computer, and I made lots of computers.
But now, in 2017, I’ve built a little machine that could do the same things my friend had designed.
