I love my scientific calculator. I've been using it a lot. Now that my high school exams are coming up I've been using it on my I pod.

*2012-10-28*

Excelente aplicación!! Muy fácil de usar, 100% recomendable.

### 1/5 — Skip the ads

*2012-07-31*

Can't get rid of the ads even if you made a purchase.   There is no way to completely clear the calculator.   Not worth the money.
