We were given a graphing calculator. I don't know why.
In the context of Math 12, here's my ratings.
| ARITHSER.83P | Arithmetic Series | Slightly useful. |
| ARITHTRM.83P | Arithmetic Term | Slightly useful. |
| CUBIC.83P | Cubic Polynomial - forget what it does (read: not useful). | |
| DISTANCE.83P | Distance - fairly useful. | |
| DIVPOLYN.83P | Divide Polynomials - slightly useful. | |
| FACTOR.83P | Factor Polynomials - very useful. | |
| GEOSEQ.83P | Geometric Sequences - slightly useful. | |
| MIDPOINT.83P | Midpoint - fairly useful. | |
| PERCDIFF.83P | Percentage Difference - fairly useful. | |
| RECURSE.83P | Recursive Series - slightly useful. | |
