What is regrouping in subtraction?

When do students learn borrowing?

Borrowing is introduced around Grade 2 and extended to larger numbers and subtraction across zeros through Grade 4.

What it is

Subtraction takes one amount away from another to find the difference.

Why it matters

Subtraction underpins making change, comparing quantities, and checking addition. Understanding it as both 'take away' and 'difference' prepares students for negative numbers and algebra.

How to do it

Line up the digits by place value.
Subtract each column, starting from the right.
If the top digit is smaller, borrow 10 from the column to its left.

Examples by level

Beginner6 - 0 =6
Intermediate93 - 6 =87
Advanced1221 - 195 =1026

Examples are generated by the same engine as the worksheets, so they're always mathematically correct. Built to avoid repeats, not reshuffle the same handful of questions.

Common mistakes

Subtracting the smaller digit from the larger regardless of position, instead of borrowing.
Forgetting to reduce the digit you borrowed from.
Struggling to borrow across zeros.

Tips

Subtracting 0 leaves the number unchanged.
Check by adding back: answer + the number you took away should equal the start.

For parents

Have your child check each answer by adding it back to the number subtracted, it should return the starting number.

For teachers

Borrowing across zeros is a reliable stumbling block; give it dedicated practice rather than assuming it transfers.

Key vocabulary

minuend: the number you subtract from
difference: the result
