Calculus.schoolInteger arithmetic practice for children
The Integers exercise type covers arithmetic with whole numbers. A learner can practise addition, subtraction, multiplication or division on its own, or answer a random mix of the four.
Every test is generated when it starts, from the settings currently selected. That makes it possible to begin with short one-digit sums and later move to longer operands, more questions or a tighter time limit without looking for a different worksheet.
What can be configured
- The operation, or a random mix of all four.
- The number of digits in the first and second operand.
- A test length between 1 and 15 questions.
- The time limit, in minutes and seconds.
- Keypad entry or multiple choice, and how many options to show.
How generated integer questions behave
Division questions are generated with whole-number results, so a child never meets a remainder in this mode. Standard subtraction practice does not produce negative results.
Some combinations of settings are constrained to keep the generated question valid — for example the first operand cannot use fewer digits than the second in the relevant subtraction and division cases.
Who it is for
Integer practice suits children consolidating the four operations, revising multiplication and division, or building speed and accuracy with larger whole numbers.
The learner, parent or teacher chooses the settings. Calculus does not assign a school grade or curriculum level to a configuration, and it does not adapt difficulty automatically.
Can a child practise only one operation?
Yes. Choose addition, subtraction, multiplication or division on its own, or select a random mix of the four.
Does integer division produce decimal answers?
No. The Integers mode generates division questions that have whole-number results.
Can subtraction produce negative answers?
Not in the Integers mode. Practice with negative numbers is a separate exercise type that is not publicly available yet.
