Can you find the mean of: 83, 90, 79, 82, 84, 88, 86, 83, 88, 81 in your head?!? If you can add and subtract integers from -15 to 15, then this program teaches you a trick to figure it out! Great for SATs, GREs, and students of Algebra through Calculus.


There were 5 topics in version 1.0. There are 17 topics in version 1.01. I expect to add 5-10 more each month, but the app is well worth the 99 cents already! The topics are listed below:

Algebra Shortcuts And "Proofs"

Chapter 1: Axioms

Chapter 2: Addition and Subtraction Tricks

Chapter 3: Chicken And Rabbit Problems

Chapter 4: Averages

Chapter 5: Weighted Averages


Calculus Shortcuts for Calc AB (single variable)

NOTE!! Calculus tricks are MUCH more difficult to prove and use.

BSC Calculus Grapher


This application graphs numerical (NOTE: numerical) integrals and derivatives of user-defined functions. Inputted functions may include polynomials, sin, cos, tangent, square root, and combinations of these. Left and right Riemann Sums may also be displayed and are part of the programming.


BSC Wordtionary


Guess the right word! 10 points for getting it right after the first set of hints and less points for using more hints.


For Example:

Find a word that deals with "FOOD" and rhymes with "bandana."
Extra clue #1: it starts with a 'b."

Extra clue #2: it has 6 letters.
Extra clue #3: The word is "banana" and you must type it in to continue.


BSC Number Dictionary


Find out if 36 is a triangular number!  Find out of 81 is a power of 3!


BSC Problem Generator


Work your way up from counting to multiplying 4 numbers and more.  Straight up arithmetic practice.  Calculate till ya drop!
