Click "Arrow" to change to opposite direction

There are 2 methods to enter answer.
Method 1) Key the answer into yellow field directly via real keyboard.
Method 2) Click the button of virtual keyboard on screen.
Method 1)  Each digit is always entered from left to right. You can enter '.' (decimal number) and '' (negative number) Do not enter , (comma) in the answer. 
Method 2)  You can control the direction of each digit. It may be entered "from left to right" or "from right to left". 
The arrow shows the direction.
The arrow points to left means that each digit of answer is entered from right to left
The arrow points to right means that each digit of answer is entered from left to right
Click at the arrow to change it to the opposite direction.
Click Delete button to delete the last digit entered. The direction of deletion according to the direction of entering
Enter button performs the same function as Confirm button

Sound Effect

Define the difficulty of maths questions.
Cat game generates maths questions according to the properties in blue field below. So you can control the difficulty of questions.
Enter the range of the first operand and the second operand and tick for additional properties then slide up to click 'Restart' to play Doll collection game .
Define the following details for cat game configuration.
1.  Range of operands
The default value of the first operand is in range 0  99. The default value of the second operand is in range 1  9.
Please keep in mind that the second operand must not be 0. The result cannot be computed if divisor is zero.

2.  Negative number
The default does not allow negative number. If you allow negative number, tick in check box of negative.
Not tick in check box of negative means negative number is not allowed.
If negative number is allowed, sign + or  is randomed first then number in range is randomed later. So you have a chance to get both
positive and negative numbers.
If negative number is not allowed, only number in range is randomed. So you never get negative numbers.

3.  Decimal places of operand
The default does not allow decimal places. Not tick in check box of decimal places means not allow decimal places.
To tick in check box of 1 decimal place means 1 digit is randomed for 1 decimal place. If zero is randomed, it becomes an integer such as 15.0 = 15
To tick in check box of 2 decimal places means 2 digits are randomed for 2 decimal places. If the second decimal place is zero, it becomes 1 decimal place such as 38.20 = 38.2
If the first and second decimal place are zero, it becomes an integer such 17.00 = 17

4.  Decimal places of answer
To tick in check box of 1 decimal place means that if it is indivisible, the result is rounded to 1 decimal place.
To tick in check box of 2 decimal place means that if it is indivisible, the result is rounded to 2 decimal places.
Not tick in check box of decimal place means that it is always divisible i.e. not allow game to generate indivisible questions.
The default is divisible.

Example 1
The first operand is in range 2  99.
The second operand is in range 2  9.
Negative numbers are allowed.
All questions are divisible.
Examples of questions created from this configuration.
27 ÷ 3
56 ÷ 8
24 ÷ 6
63 ÷ 9
Example 2
The first operand is in range 12  999.
The second operand is in range 2  9.
The first operand and the second operand are integers.
Negative numbers are not allowed.
Questions may be disivible or indivisible. If they are indivisible, round the results to 1 decimal place.
Examples of questions created from this configuration.
15 ÷ 7
456 ÷ 6
Example 3
The first operand and the second operand are in range 2  9.
Negative numbers are allowed.
The first operand may have 2 decimal places, or 1 decimal place or may be an integer.
The second operand may have 1 decimal places, or may be an integer.
Negative numbers are allowed.
Questions may be disivible or indivisible. If they are indivisible, round the results to 1 decimal place.
Examples of questions created from this configuration.
1.34 ÷ 2
2.15 ÷ 1.4
4.8 ÷ 3.7
3 ÷ 4.5

  Maths Games+, , x, ÷ are basic maths operators. Complex formulas are composed of these basic operations. Metal calculations of these operations are essential maths skills.
Maths games are created to be tools for children to improve their metal calculation skills. Users can customize the configuration of games to control the level of difficulty.
