Funny Math - Numbers Making for iOS 7+


Tap on falling numbers to make sum ....
Funny Math - Numbers Making is an educational game to learn numbers and simple math operations (adding). With each given number from 10, user should tap on the falling numbers 1, 2, ... 9 to make a sum, which is equal to the given number. After successful tappings, you will go to next level with next number, speed of falling, speed of rotation and less time-limit.

This game is to support the "new common core standards" in teaching and laerning maths.
Learn to set strategies

To accomplish high levels (20, 30 or more), user should implement a smart strategy: one of them is to choose biggest numbers first (6, 7, 8, 9) and then choose smaller to adjust the sum. For example, in level 16 user should make a number 25,  following are some strategies:


25 = 9 + 9 + 7
25 = 9 + 8 + 8
25 = 9 + 8 + 7 + 1
25 = 9 + 7 + 6 + 3
.....


Depends on concrete situations, user can choose different strategies to make sum 25 within very short time interval (5s).

How to play?

Tap on falling numbers to make a sum, which is equal to given numbers in the limited time interval (15s -> 5s)

- Tap on ► to start new game
- If you make a right sum -> go to next level
- If you make wrong sum or time-out -> game over

Banner will be NOT showing for levels 16 and higher (making 25 or bigger numbers)

iOS App: Math Functions & Graphs



"Math Functions and Graphs" is a set of powerful tools for pupils, students, teachers in schools and researchers in the fields of mathematics, calculus and analytic geometry. Version 2.0 is a comprehensive redesign and added a lot of new features. With this version, the system supports 3 types of functions and graphs:: 

1) y = y(x) or x = x(y)
2) x = x(t) and y = y(t)
3) r = r(t)




Each of these functions mentioned above may include one or more of the basic forms of mathematical functions:

(1) Polynomials
(2) Rational functions
(3) Trigonometric functions
(4) Hyperbolic functions
(5) Ellipses & circles
(6) Flower styles
(7) Spirals
(8) Special functions

Most of the basic mathematical functions such as sin (), cos (), born (), sqrt (), exp (), log (), ln (), abs (), ... are supported. You can work with a single function or a combination of many different mathematical functions.


Special feature: The application supports working with formulas containing previously unknown parameters, denoted by the letters: a, b, c, m, n, ... For example, you may have a function with the following form:

y(x) = a * x^2 + b * x^ + c, or
x(t) = a * t + b * sin(t); y(t) = a * t + b * cos(t) or,
r(t) = a * x + b + m / (x - 1) 

where a, b, c, m are random parameters / coefficients. Applications will assign values to calculate your specific values or as graphs. The parameters that you do not enter a specific value will be assigned a default value of 1 in the calculation.



The graph features

- Draw a graph of any function of valid format
- Draw a graph with the parameter values
- Draw the tangent line to the graph (derivative is defined)
- Identify the intersections with Oy (when y = 0)
- Identify the extremes of functions (when y' = 0) 
- Export and share results

The system supports interfaces and user’s native language with 11 different languages, including:

- English
- Spanish
- Portuguese
- German
- Japanese
- Chinese
- Korean
- French
- Italian
- Russian
- Vietnamese

With all the additional features, "Math Functions and Graphs" is the best tool to support all students, teachers and academic staffs in learning, research or presentations, documents, websites, blogs, ... related to mathematics and mathematical analysis.



Most of the maths problems are easy to implement and easy to understand when we can graph functions quickly and accurately. Application "Math Functions and Graphs" help you do it right on the mobile devices such as iPhone, iPad and iPod Touch with iOS 6.1 or later installed. Applications can become a powerful tool for learning and teaching mathematics, in general and analytic geometry in particular in high school

How is a mathematician?

Definitely a mathematician!

There are two people lost in a balloon. They fly over a hill and saw two people arguing with each other very pungent. Someone needs to ask "you to ask where we are?". Two below and then looked up to debate. The wind blew hot air balloon go, then a new outlook on the bottom: "You're on a balloon!". The man on balloon says "make sure the two below are the mathematicians." "How'd you know?" Asked the companion. 

"First, the mathematicians always bickering” 
"Secondly, they always think carefully before giving the answer” 
"First three: their answer is always extremely accurate “ 
"Fourth: the exact answers are often useless!”



Mathematical Solution

Basic difference between mathematicians and physicists is that, if asked them "how to pull a nails played a half in the wood"? Then physicists will suggest that, if a human is extracted with force N where N is greater than the total friction pressure as well as other pieces of wood on the nails, the nails are removed. 

But mathematicians will first prove that even when nails are closed flooded into the wood it can still spit out. Then they can prove to be closed nails plug half submerged into the wood with their famous phrase "bring back to the original problem "!

Game: Match flags to countries


How many nations/regions can you name? Do you remember what their flag looks like? "Match Countries and Flags" is a free educational game to help users train their memory, to get to know and remember the name (in English) and flag of 200 countries and regions around the world.

The main screen of the application is divided into 20 plots. Each time you play, the game will select the name and flag of 10 random countries / territories/ states and put them in random order into 20 covered boxes on the screen. The player has to pair up the name and the corresponding flag of a country. If you choose correctly, the two boxes will remain open, if not both boxes will close automatically. Players will succeed if all 20 boxes are open, and they can proceed tp the next round.



The level of players will be evaluated based on the previous results ( of at least 10 games). The lesser the attempts used, the higher the level. After each round, the application will display the current level of the players based on the following levels:

0 - star: Beginner
1 - star: So-so
2 - star: Experienced
3 - star: Professional
4 - star: Guru
5 - star: World-top

Players can share results and experiences with their friends via facebook or twitter. The game runs on iOS 7.0 & later devices.

Game for iOS7++: Billiards 123

Billiard is the family of cue sports and games played on a pool table having six receptacles called pockets along the rails, into which balls are deposited as the main goal of play. Now you can see this game on the iPhone screen, iPod touch or iPad with the subtle movements of the balls and some additional interesting changes:

1) Mines (black balls) are added, if your white ball hits one of the mines, it will explode and you will lose 1 out of 5 white balls for each game. The number of mines on the table equals the level you reach. For example, if you're at level 5, the table will have 5 mines with uncontrollable movement due to collisions with other balls - a big challenge for the player!

2) You need to hit the white ball so that it moves and hits the other balls numbered 1 to 9 in numerical order. With each accurate collision points will be added with value depending on: the number of the balls (1, 2, 3, ... 9);the level at which you are playing; and the number of consecutive collisions after each shot. For example, a blow your balls hits No. 1, then No. 2, and No. 3,the points for hitting No. 2 will be doubled, and that for hitting No. 3 will be tripled.

The game ends when you've hit 5 mines in total. You can also share your results with friends on Facebook or Twitter. Challenge your billiard skills with the game requiring precision, dexterity and imagination of geometry!

Fast and Dangerous Monkey (iOS7++)

The monster robot is trying to catch a monkey. The monkey is running to escape off. On the way the monkey meets flying bricks and sometime luckily meets a banana bunch! Try to catch banana bunches and do not impinge a bricks, it costs a death! Your score is a number of bricks you have passed.



Just touch on the screen to up a bricks if needed and to down a banana bunch if it is flying too high. Very simple, but it is challenging racing game!

Geometry Drawer for iPhone

Plane Geometry Drawer is an application for iPhone users, providing a set of tools in drawing and solving Mathematics problems related to plane geometry.
