How subtraction with regrouping works
Subtraction problems ask students to find a difference, and regrouping (also called borrowing) is the step where a student renames one ten as ten ones, or one hundred as ten tens, when the top digit is too small. This generator writes sets at your grade and difficulty, with an answer key.
The place-value work underneath
Subtraction runs through 1.OA.C.6 (within 20), 2.NBT.B.5 (within 100), 3.NBT.A.2 (within 1,000), and 4.NBT.B.4 (the standard algorithm). The extra step compared with addition is the regroup: students notice the top digit is smaller, take one from the next place, and adjust both digits.
Ways to shape the output
Set the range: within 10 for kindergarten, 20 for 1st grade, 100 for 2nd, and three or four digits for 3rd and 4th. Then pick a regrouping option:
No regrouping, for introducing the method
Regrouping in every problem: 504 − 287 = 217
Borrowing across a zero: 500 − 268 = 232, 403 − 157 = 246
Mixed sets for spiral review
Missing-number items (72 − __ = 45) for early algebraic thinking
Classroom fits
Use a 15-problem page as a warm-up, a reteach set when a quiz shows regrouping errors, or summer review. Pair it with the addition problems generator for a balanced fluency block.

What teachers say
Teachers across subjects, from AP history to astrophysics, on grading with GradeWithAI.
“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”
“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”
“More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.”
“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”
“GradeWithAI [provides] students with timely individualized feedback on their homework assignments and formative assessments. This is a job that is virtually impossible for a teacher to do on a regular basis.”
“Students have also appreciated the consistency and immediacy of the feedback I can provide through GradeWithAI. This has enabled them to make necessary corrections and achieve their desired scores on any assignment.”

Yes. Ask for 'subtraction across zeros' and the generator writes problems with a zero in the top number, such as 600 − 347, so students practice renaming twice.
Each item has an answer line, and the page is plain text. Students who need to stack the numbers can copy each problem into a column on scratch paper or graph paper you hand out.
Addition, subtraction, multiplication, division (including long division), fractions, decimals, ratios, percents, pre-algebra, Algebra 1 and 2, and geometry.
Yes. Ask for word problems in the description, and add a context such as sports, animals, or food if you like.
Pick the grade, which sets the kind of numbers and operations, then choose easy, medium, or hard.
Yes. Every problem has an answer, printed on a separate page. Work a few problems yourself before handing the set out, since AI-generated math can contain mistakes.
No. It writes problems. To grade completed work, upload it to GradeWithAI, which reads handwritten math and gives partial credit under your rubric or answer key.
Yes, with no account.
