This is a math-quiz program where you are faced with rather difficult math questions, good luck trying to solve these. With effort a high-school student should be able to beat this quiz. There is one hard integral in the quiz but there are ways to cheat making that question a lot easier.
You will get a nice reward for finishing the game, you can save that as a screenshot.
This is a somewhat useful program that consist of a collection of auto-solvers. You push a buttom with green letter to select the solver you need
A: calculate A!
B: calculate A!/B!
The issue with using the built in factorial calculator is that it is limited to 69.5! and below (due to TI84+ giving an error message if any anser is bigger than 10^100, this is for aesthetic reasons only).
One current limitation is that it doesn't work for negative numbers so it's not the complete gamma-function, still better than the built-in factorial that is limited to half-integers
C: solve a second order equation
The roots will be given as the calculator variables (X, Y).
D: solve a cubic equation
The roots will be given as the calculator variables (X, Y, Z).
E: solve a forth order equation
The roots will be given as the calculator variables (X, Y, Z, θ).
F to N solves for a triangle where 3 is known (area, angles, sides)
O: this will calculate the number of permutations for arbitrary number of object types.
If you input (3,4,5,6,0) it will calculate (3+4+5+6)! / 3! / 4! / 5! / 6!
If you input (3,4,5,-30) it will calculate 30! / 3! / 4! / 5! / 18!
What's nice about TI-basic programming is the fact that you actually have full control over the device.
The bad aspect of it is that the calculator is very slow and is also very limited in resolution (95*63) which is why most people move over to matlab or other sortware once they need to do more advanced calculations.
One advantage with ti84+ is the fact that it is highly durable, it doesn't break easily.
