You have a calculator that does algebra
! For three variables
!
I didn't even know that such things existed. My school sells the fx-82MS now, but they had the fx-82TL when I started high school. I have a fx-100AU.
We've all always wanted to be able to key in an equation and get an answer, and we believed that it was impossible
.
I guess that a calculator that can do that wouldn't be "board approved" though and we wouldn't be able to take it into our exams though.
