If you are in Line Mode with a Line input, you can switch to MultiLine Font which enables you to show a series of calculations on a scrolling screen. If you choose the small font, you can fit even more lines on the screen at one time. Great for a series of fast calculations.

We know that we can press S=D to change an exact result to a decimal answer, but on the Classwiz there are two ways that can give you a decimal approximation. There is the approximately equal to feature and you can change the setting so that you get a decimal result every time.

This video shows you how you can change the battery on a Casio Calculator that takes an AAA battery and replace it with a rechargeable AAA battery. These are typically models that do not have the solar panel, such as the fx-83GTPLUS and will have a raised projection at the top of the reverse side of the calculator.

The process is very simple, you just need to remove 6 screws from the back of the calculator and the back of the case should come away from the front. The battery can just be popped out of the housing and replaced. I show the Panasonic Eneloop in the video, which is a recommended rechargable battery.
