*On this page, you will learn how to set up your custom Math Puzzle difficulty. *

In the math puzzle mode, the player has to solved mathematical problems to reveal the puzzle pieces. For every puzzle game, a new set of problems is randomly generated. The “Math Puzzle Settings” allows you to adjust the difficulty of the math problems to your target audience.

To open the “Math Puzzle Settings” page:

1) Select the puzzle mode “Math”.

2) Click on the button “Custom” under the “Math Difficulty” section.

## The Math Puzzle Settings page

The first option *# of questions* sets an upper limit for the number of math problems to be generated. Please note that this is an upper limit: if your puzzle has only 9 pieces and this limit is set to 12, only 9 math problems will appear.

In the middle section of the page, you can select the basic operations for the math problems. To select or unselect an operator, just click on the checkbox close to the wanted operator. At least one operator must be checked.

In the lower part of the page, example of math problems are automatically generated for every configuration change.

Once you finish adjusting the configuration, just click on the close button at the top right corner of the page. Your settings are automatically saved and will be used when the Custom math difficulty option is selected.

## Configuring the operators

For each operator, you can select a minimum and maximum number and an upper value. Next to the operator there is a list of pre-configured number ranges. If none of these suits your needs, select customize values to set each individual parameter manually.

The meaning of these parameters depends on the operator being configured:

**Addition**: The minimum and maximum value refer to the terms and the upper value refers to the sum.

*term *+ *term *= *sum*

- Subtraction: The minimum and maximum value refer to the subtrahend and the upper value refers to the minuend. The subtraction problems always have a zero or positive result.

*minuend *– *subtrahend *= *difference*

- Multiplication: The minimum and maximum value refer to the factors and the upper value refers to the product.

*factor *× *factor *= *product*

- Division: The minimum and maximum value refer to the divisor and the upper value refers to the dividend. The division problems always have a zero or positive integer result with no rest.

*Dividend *÷ *divisor *= *quotient*

## Understanding the *up to* value

The upper or *up to* value allows you to use slightly bigger numbers while still limiting the problem difficulty.

For instance, when configuring the addition operator, if you select the minimum and maximum value for the terms as **1** and **9** respectively, the biggest possible sum would be **9 + 9 = 18**.

Nevertheless, if you set up the *sum up to* value to **12**, the puzzle will generate problems like **9+3** or **8+4**, but not **8+5** or **9+7** (as the result would be bigger than 12).
