i_b Mathematics SL Topic 2

This new application i_b Mathematics SL Topic 2, consists of 400 new exercises on
Topic 2 - Functions and Equations
(all answers are provided) divided in 4 subjects - 4 exercise categories.

Subject A: 120 exercises - True - False,
Subject B: 120 exercises - Multiple Choice,
Subject C: 80 exercises - Multiple Choice with diagram
Subject D: 80 exercises - Problem Solving.

The application presents only my point of view on the Topic 2 - Functions and Equations. Exercises emerged from twenty years of experience in teaching of Mathematics.
There are 50 separate exercises for each paragraph as follows:

15 exercises in Subject A, True - False for each paragraph (8x15=120)
15 exercises in Subject B, Multiple Choice for each paragraph (8x15=120)
10 exercises in Subject C, Multiple Choice with diagram for each paragraph (8x10=80)
10 exercises in Subject D, Problem Solving for each paragraph (8x10=80)

In this Topic, there are 8 paragraphs:

2.1 Concept of function,
2.2 The graph of a function,
2.3 Transformations of graph,
2.4 The quadratic function,
2.5 The reciprocal function,
2.6 Exponential-Logarithmic functions
2.7 Solving equations
2.8 Applications

Students can access all exercises of the application in two ways.
A: as a TEST
Student can run as many TESTS he wants with 18 (=5+5+4+4) exercises in four subjects (Subject A: True - False, Subject B, C: Multiple Choice, Subject D: solve problems.). The exercises, in this case, are chosen randomly, from the base of 400 exercises, by the application and therefore two TESTS are never same since, without exaggeration, million combinations of exercises are generated. The student in a short time can control his knowledge without being tired but most of all, without the time consuming writing.
B: by serial access
The student can run the exercises he wants from each paragraph, by practicing all the exercises at each Subject separately. The student can choose to do all the exercises of every paragraph that are stored in the base (for example, Subject A) or a few of them, since there is STOP button to end the process. Because access in this case is serial, the student has the ability to continue practicing the exercises some other time from the point he/she stopped. Similarly the student can run all the exercises, or those he wants, from Subject B, e.t.c.

-Learn and Play
-Ideally for the schools (tablet,hdmi,projector), teachers, students
-It does not require internet connection

The application will work on phones and tablets android of various sizes and screen analysis (from 240x320 and up).
