 # Math: Unknown

## Step-by-step Math Calculation Game Created Exclusively for iPad, iPhone and iPod touch.

### No more frustration with arithmetic + – × ÷ # Is Your Child Struggling with Math?

### Frustrated with ?

Always forget carrying (regrouping), therefore the calculation results are wrong.

### Multiplication

Don’t understand which digits should be multiplied and where to place the calculation result. ### Long Division

Don’t know how to do long division with remainders. Don’t understand when to multiply or when to subtract.

### Subtraction

Don’t understand how borrowing in subtraction works especially when there are so many zeros. # Don’t Ever Give Up!

## Sometimes Math is Hard.

### Math: Unknown is much more than a math game. It is a step-by-step math calculation game which will teach users how to calculate in the correct order rather than just asking only the final calculated results.

The app consists of four basic arithmetic operations which are addition, subtraction, multiplication and division. In order to get started, users who are new to arithmetic can learn from animated calculation guides showing step-by-step procedures of solving each type of operation. It is also helpful for experienced users as a quick reference.

Generally, addition and subtraction may be difficult for users who just start learning math especially when questions require carrying or borrowing (also called regrouping). The app helps users to visualize the process of carrying and borrowing in the way it will be done on paper. Once users understand how these operations work, they are ready to learn multiplication and division.

For most students, division is considered as the most difficult arithmetic operation to solve. It is a common area of struggle since it requires prior knowledge of both multiplication and subtraction. To help users understand division, the app uses long division to teach all calculation procedures. Relevant multiplication table will be shown beside the question. Users will have to pick a number from the table which go into the dividend. Multiplication of selected number and divisor is automatically calculated, but the users have to do subtraction and drop down the next digit themselves. Learning whole calculation processes will make them master it in no time.

### Practice

• + Starting from Basic Addition
• + Gradually increases difficulty with more number of digits
• + Automatically shows carrying (regrouping) the same way as doing it on paper.

### Multiplication

• × Starting with Basic Multiplication
• × More number of digits as level progresses
• × Show carrying in early levels
• × Relevant multiplication table is shown when necessary ### Subtraction

• – Starting with Basic Subtraction without borrowing
• – Borrowing is needed in higher levels
• – Borrowing is visualized by a single button press at the right time

### Long Division

÷ Detailed Long Division
÷ Display relevant multiplication table for quick reference
÷ Multiplication is done automatically once a correct quotient was picked
÷ Calculate it all from top to the remainder

### “Math: Unknown” is a step-by-step math calculation game which will teach players “how” to calculate in the correct order.

Unknowns are numbers you have to solve.
The more players solve unknowns, the more they know.

Players will focus on 4 kinds of math operations i.e. addition, subtraction, multiplication and long division. It’s like having a personal math tutor with them everywhere.. all the time.

The game has 4 main arithmetic operations. Each operation has 2 sets (A and B) and each set contains 8 levels of difficulty with unlimited number of problems. So they can play as many as they want, there is no limitation. The score (stars) they got will be accumulated for each set to compete with other players via Game Center.
