Mixed Basic Operations
Under Review
With Mixed Basic Operations you can create a random mixture of basic operations equations.
Note
Many of the options available for single operation basic exercises sets are available for Mixed Basic Operations, but not all. In some cases you may want to use the single operation exercise sets.

Select the operations for the exercise set
By default, only Addition questions are selected. Click in a check box by an operation name to include that operation in the mix of operations for the exercise set.
Note
The settings for each operation are listed further down the options pane, but an operation name must be checked in order for that operation to be included in the mix of equations.
Change the question orientation
Select whether to have the questions appear in vertical or horizontal orientation. To set the question orientation, select the desired orientation option (Vertical or Horizontal) for the Exercise Orientation option in the options pane.
Addition
Addend 1 and 2
Change the range of values for addition
To achieve values within a set range, set the the high end of the range and the low end of the range.
-
To set the high end of the range, select the input field for the Range High option in the options pane and enter a new value to the maximum allowed for that exercise.
-
To set the low end of the range, select the input field for the Range Low option in the options pane and enter a new value to the minimum allowed for that exercise.
Note
To locate the range for any particular option, check the definition area at the bottom of the options pane when an option is selected. Some exercises allow negative values to be entered for either the high or low end of the range by using the hyphen as the negative sign, i.e. -10, -999, -1000.
Change the distribution of values for addition
This feature determines whether the randomly selected numbers for the questions are generated completely at random (normal) or if a weighted selector is used (balanced). The balanced setting ensures that small numbers are given an equal chance of being selected along with larger numbers.
Limit Sums
Apply sum limits
To limit the sums as defined by the Minimum Sum and Maximum Sum options, select the check box for the Apply Limits option in the options pane.
Note
In some cases, this option may override settings for addends.
Tip
If you would like all questions to add up to 10, set both the Minimum Sum and Maximum Sum to 10.
Set the minimum sum
-
To set the minimum sum, select the input field for the Minimum Sum option in the options pane.
-
Type a new value in the field. Valid range is 0 to 99,999.
Set the maximum sum
- To set the maximum sum, select the input field for the Maximum Sum option in the options pane.
To set the distribution of values, select the desired distribution option (Normal or Balanced) next to the Distribution option in the options pane.
- Type a new value in the field. Valid range is 0 to 99,999.
Subtraction
Minuend and Subtrahend
Change the range of values for subtraction
To achieve values within a set range, set the the high end of the range and the low end of the range.
-
To set the high end of the range, select the input field for the Range High option in the options pane and enter a new value to the maximum allowed for that exercise.
-
To set the low end of the range, select the input field for the Range Low option in the options pane and enter a new value to the minimum allowed for that exercise.
Note
To locate the range for any particular option, check the definition area at the bottom of the options pane when an option is selected. Some exercises allow negative values to be entered for either the high or low end of the range by using the hyphen as the negative sign, i.e. -10, -999, -1000.

Limit Differences
Apply sum limits
To limit the differences as defined by the Minimum Difference and Maximum Difference options, select the check box for the Apply Limits option in the options pane.
Note
In some cases, this option may override the setting for the Subtrahend to ensure no subtraction question has a difference outside the desired limits.
Set the minimum difference for subtraction
-
To set the minimum difference, select the input field for the Minimum Difference option in the options pane.
-
Type a new value in the field. Valid range is 0 to 9999.

- To set the maximum difference, select the input field for the Maximum Difference option in the options pane.
To set the distribution of values, select the desired distribution option (Normal or Balanced) next to the Distribution option in the options pane.
Tip
If you would like all questions to have a difference of 10, set both the Minimum Difference and Maximum Difference to 10.
- Type a new value in the field. Valid range is 0 to 9999.
Multiplication
Generate exercises with no regrouping
The No Regrouping option can be used to generate multiplication questions that require no regrouping to solve. This option will override range settings for multiplicand and multiplier.
