The calculator makes calculations fun. You can see the calculation laid out on the screen, you can correct any mistakes easily, and it does complicated calculations so quickly.

I like the pictures and graphs – a picture means so much more to me than a formula.

I like to be able to store numbers, formulas and simple programs in the calculator and I am still amazed to discover that they are still there next time I turn on the calculator.

I like the layout of the keyboard, all the numbers together away from the more advanced keys.

It saves me so much time. I like to feel that I have all that power in my pocket!

All these students have their own favourite aspects of the calculator and, as you get to know yours, you will develop your own preferences. Some advantages of the TI-84 are given below, but as you work with the calculator you may well find other useful aspects to add to the list.
