- Statistical Functions Including:
- Mean and Standard Deviation.
- Linear Estimate and Linear Regression.
- Correlation Coefficient.
- Area Under Standard Normal Distribution to the left of x (Q) and x given area (Q^-1).

- Factorial (n!).
- Hyperbolics.
- More conversions including gallons/liters, and decimal hours/hours.minutes.seconds.
- Percent Change.
- X Squared (Shifted so it took two key strokes anyway but it conserved stack space.)
- More storage registers: 0-8 and .0-.5 (They were split this way because the statistical functions needed 6 registers and this provided a clean split between stat and "normal" registers.)
