Graphical Calculator

It is 1985, and CASIO
Just announced a new calculator; FX-7000
It graphs, and it also has got programming
422 bytes for you!

I'm such a nerd
I love my calculator
Mathematical, it just works!

Then came along Texas Instruments, they hit it big
TI-81, it was huge
Updates came along, TI-84
It was a success and still is today, now!

I'm such a nerd
Graphical calcuator
Educational, it just works!
