Struggling with calculus?  Own a TI-89 Titanium?

Tired of missing steps? Homework taking too long?

My name is Tom and I program TI calculators to make calculus much easier step by step and showing all work.

Welcome to where your TI-89 Titanium calculator shows you exactly what you really want.  The correct answer step by step, right on your TI-89 calculator screen. My programs are are about doing, about practicality, about reality.  They are from many midterms, finals, quizzes and homework. My programs show work for all kinds of calculus solutions line by line at your own pace so you can write it down on tests, homework, whatever.

I have been selling these programs on ebay for years, check my 100% positive feedback HERE

You get all 90+ calculus programs below for one low price.

Many professors, textbooks and even solution manuals, skip steps and don’t show work to save time or space. We as students then have to spend extra hours pondering the problem as to how it got from there to here. Find out whats really going on with any calculus problem I’ve programmed.

My programs and my TI-89 got me through college calculus stress free so I could move on with my life:)

Here’s how the program works:

1. Choose a calculus problem from the menu list you want to solve

2. Enter your variables

3. Press ENTER repeatedly and the solution shows itself STEP BY STEP

4. Study or write the solved solution down STEP BY STEP

SATISFACTION GUARANTEED or I will give you 110% (yes, that’s 110%) of your money back, no questions, no problem. Everyone has loved the programs.. Work smarter not harder..Clever is King

Easy to Download, Install and Use

After purchase, download the folder with the programs in it then transfer them onto your calculator via USB cable…simple and fast.
