Subtraction With and Without Borrowing — Parent Guide

Once your child is comfortable with basic subtraction, the next milestone is understanding ‘borrowing’ — also called regrouping. This is where many parents get stuck too, since it is rarely explained in simple terms.

This guide breaks down the difference between subtraction without borrowing and with borrowing, and gives you an easy way to explain both to your child.

What is Subtraction Without Borrowing?

Subtraction without borrowing is the simplest form — every digit on top is equal to or bigger than the digit below it in the same column, so no adjustment is needed.

Example: 57 − 23. In the ones column, 7 is bigger than 3 (7 − 3 = 4). In the tens column, 5 is bigger than 2 (5 − 2 = 3). Answer: 34. No borrowing required.

💡 Quick rule: if every top digit is bigger than the digit below it, no borrowing is needed at all.

What is Borrowing (Regrouping) in Subtraction?

Borrowing happens when the top digit in a column is smaller than the bottom digit, so we cannot subtract directly. We ‘borrow’ 1 ten from the next column to make the top number big enough.

Example: 52 − 28. In the ones column, 2 is smaller than 8, so we cannot subtract directly. We borrow 1 ten from the tens column, turning 2 into 12. Now 12 − 8 = 4. The tens column becomes 4 (borrowed) − 2 = 2. Answer: 24.

💡 Think of borrowing like exchanging money: you borrow a ₹10 note and break it into ten ₹1 coins to make up the difference.

How to Explain Borrowing to a Child — Step by Step

Step 1: Master Subtraction Without Borrowing First

Never introduce borrowing before your child is fully confident with simple column subtraction. Rushing this step is the most common cause of confusion.

Step 2: Use Place Value Blocks

Use ten-blocks and single-unit blocks (or bundles of ten sticks). Show your child physically breaking one ten-block into ten single units when the ones column runs short.

Step 3: Use the ₹10 Note Example

Indian children relate well to money. Show that a ₹10 note can be exchanged for ten ₹1 coins — this is exactly what ‘borrowing’ does with tens and ones.

Step 4: Practice With Small Numbers First

Start with two-digit numbers only, where borrowing is needed just once, before moving to bigger numbers with multiple borrowing steps.

Step 5: Write It Out Together, Slowly

Solve 3 to 4 problems together on paper, saying each step out loud: ‘The ones column is too small, so we borrow one ten.’ Repetition builds the pattern into memory.

Subtraction Without Borrowing vs With Borrowing

• Without borrowing: every top digit is bigger — subtract straight down each column
• With borrowing: a top digit is smaller — borrow one ten (or hundred) from the next column first
• Without borrowing is taught first and mastered before borrowing is introduced
• Borrowing needs strong place value understanding (tens and ones)

Common Mistakes Children Make

• Subtracting the smaller number from the bigger regardless of position, instead of borrowing
• Forgetting to reduce the column they borrowed from by 1
• Attempting borrowing before place value (tens and ones) is solid
• Getting confused with multiple borrowing steps in larger numbers

When Do Kids Learn Borrowing in Subtraction?

In most Indian school curricula (CBSE and ICSE), subtraction without borrowing is taught in Grade 1, while borrowing (regrouping) is usually introduced in Grade 2, around age 7 to 8, once place value with tens and ones is well understood.

FAQ

Q: What is borrowing in subtraction for kids?

Borrowing means taking 1 ten from the next column when the top digit is too small to subtract directly, so the calculation can be completed correctly.

Q: How do I explain borrowing in subtraction simply?

Compare it to exchanging a ₹10 note for ten ₹1 coins — you are converting one ten into ten ones so you have enough to subtract.

Q: At what age do kids learn borrowing in subtraction?

Most children learn borrowing in Grade 2, around age 7 to 8, after they are confident with subtraction without borrowing.

Q: Why does my child avoid subtraction with borrowing?

Borrowing needs strong place value understanding. If tens and ones are not fully clear yet, borrowing will feel confusing until that foundation is built.

Q: Should I teach borrowing before or after simple subtraction?

Always after. Simple subtraction without borrowing must be fully mastered first, or borrowing will feel like an entirely new, harder skill.
