Choose an operation, number range, and problem count to create a fresh browser-local worksheet and answer key, then print or save it as PDF.
The primary worksheet above stays first. This studio reuses WTA144Classroom.worksheet(), adds a deliberate operation subset and page layout, and exports the exact generated rows for answer-key handoff.
The fingerprint identifies the current rows; it is not a regeneration seed.
Choose addition, subtraction, multiplication, exact-division, or mixed practice; set the number range and problem count; then generate and print a worksheet with its answer key.

Use the tool first, then apply these checks to verify the inputs, interpret the result, and hand it off without displacing the primary workflow.
A mixed worksheet is useful only when the intended skill really is operation selection. For focused fluency, choose one operation or a deliberate subset so the student is not spending most of the task deciding which rule applies. Keep the number range aligned with the facts or written method being practiced rather than treating a larger range as automatically better.
Exact-division questions are constructed to avoid remainders, while the no-negative option changes subtraction problem order. Review a few generated rows before handing out the sheet so those constraints match the lesson. If negative integers or remainders are part of the target skill, use a specialist workflow instead of silently accepting a simplified worksheet.
A regenerated worksheet is intentionally different. Export the question-and-answer CSV or keep the sheet fingerprint with the printed copy when another person must verify that an answer key belongs to the same generated set. The fingerprint identifies the current rows; it is evidence, not a seed that recreates them later.
Two, three, or four columns change page density without changing the arithmetic itself. Pick a layout that leaves enough writing space for the expected method, then preview or print at the actual paper size. For long-form work, fewer columns can be more useful even when the same number of questions fits on one page.
