Features

Game mode and Practice mode

Game mode which has two levels: Hard mode and Easy.
The questions in the two mode are same but required time and score are different.
After 3 questions, you can review the questions.

Practice mode which has five sections:

1. Calculation.
2. Equation.
3. Function.
4. Geometry
5. Calculus.

Each section has more than two levels and categories.
Every question is programmed to practice several times by changing value in the questions.
So you can grab the core of question by practicing.

1. Calculation
A. Basic:
B. Fraction:
C. Factorization:
D. Rationalization
E. Recurring Decimals

2. Equations
A. Linear Equations 1
C. Inequalities
D. Absolute values

3. Function
A. Proportions
B. Invert Proportions
C. Linear Functions

4.Geometry
A. Lengths
B. Areas
C. Angles
D. Pythagorean theorem
E. sin, cos, tan
F. Law of sines

5. Calculus
A. Basic
B. Differentiation
C. Integration

Recently changed in this version

"Examination 1 and 2" are added in "Examinations" of "Geometry" section. It would be a certain story to reach the answer.

"Similarity 1 and 2" are also added in Geometry.
