Algebra helper - This is a nice program with many functions!

Period table - A good periodic table.

Circles - Allows you to enter a property of a circle, and it returns 5 properties of a circle, includes, radius, diameter, circumference, area, and volume. Great for geometry!

Cramer's rule - Uses Cramers rule to solve a system of equations.

Distance formula - This is a great time saver. It calculates the distance between two points!

Slop finder - Gives the slope, y intercept, and puts everything in slope intercept form (y=mx+b) after you give it two ordered pairs.

Foil - This is a nice program that does foil for you. It saves a lot of time!

Geometry helper - This is a great program with many formulas!!!

Quadradic formula - I've tried this one and it works good!

Quadratic formula - This is slightly better than the other quadratic formula.(above) It has more information to give about the points and more options, but the other one is a much smaller file and it does the normal solving so pick which one you like!
